    Abstract [en]

    Tomato leaves can be infected with various infectious viruses and fungal diseases that drastically reduce tomato production and incur a great economic loss. Therefore, tomato leaf disease detection and identification are crucial for maintaining the global demand for tomatoes for a large population. This paper proposes a machine learning-based technique to identify diseases on tomato leaves and classify them into three diseases (Septoria, Yellow Curl Leaf, and Late Blight) and one healthy class. The proposed method extracts radiomics-based features from tomato leaf images and identifies the disease with a gradient boosting classifier. The dataset used in this study consists of 4000 tomato leaf disease images collected from the Plant Village dataset. The experimental results demonstrate the effectiveness and applicability of our proposed method for tomato leaf disease detection and classification.

    Abstract [sv]

    Industrialismens genombrott innebar en av de största förändringarna i samhället någonsin. Människors liv förändrades i grunden och deras tid kom att indelas i arbete, fritid och vila. De offentliga parkernas betydelse för stadsborna betonades ofta under 1800-talet. Frågan är vilken roll parker och trädgårdar fick vid fabrikerna.

    The Paradox of Self-Fertile Varieties in the Context of Self-Incompatible Genotypes in Olive2019In: Frontiers in Plant Science, E-ISSN 1664-462X, Vol. 10, article id 725Article, review/survey (Refereed)
    Abstract [en]

    Olive, representing one of the most important fruit crops of the Mediterranean area, is characterized by a general low fruit yield, due to numerous constraints, including alternate bearing, low flower viability, male-sterility, inter-incompatibility, and self-incompatibility (SI). Early efforts to clarify the genetic control of SI in olive gave conflicting results, and only recently, the genetic control of SI has been disclosed, revealing that olive possesses an unconventional homomorphic sporophytic diallelic system of SI, dissimilar from other described plants. This system, characterized by the presence of two SI groups, prevents self-fertilization and regulates inter-compatibility between cultivars, such that cultivars bearing the same incompatibility group are incompatible. Despite the presence of a functional SI, some varieties, in particular conditions, are able to set seeds following self-fertilization, a mechanism known as pseudo-self-compatibility (PSC), as widely reported in previous literature. Here, we summarize the results of previous works on SI in olive, particularly focusing on the occurrence of self-fertility, and offer a new perspective in view of the recent elucidation of the genetic architecture of the SI system in olive. Recent advances in research aimed at unraveling the molecular bases of SI and its breakdown in olive are also presented. The clarification of these mechanisms may have a huge impact on orchard management and will provide fundamental information for the future of olive breeding programs.

    Dynamic simulation and techno-economicevaluation of a seasonally insulated hybridgreenhouse concept for subarctic climates2023Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Swedish authority for social protection and preparedness, MSB, believes that the self-sufficiency of the country must be strengthened in order to be prepared for a crisis. Presently, Sweden is only 50% self-sufficientwhich is very low compared to its neighboring countries; and it is worse the further north you go. One solution could be to increase the production of food, for example vegetables, but the number of greenhouse operations in Sweden are already dwindling due to the inhospitable climate, which makes it expensive to keep up all-year cultivations. Norrbotten, the northernmost part of Sweden, has the highest heat demand for greenhouses in the country. One option could be to set up operation in heavily insulated buildings and rely on artificial lighting, in so called plant factories. Though, these are expensive, electricity intensive and have generally lower yields.

    This report will cover the development, validation, and performance of a dynamic model of a new greenhouse concept, developed for subarctic climates. The greenhouse is meant to utilize the strengths of both glass houses and plant factories to optimize the profits for a year-round operation. This, to find an alternative solution to the self-sufficiency problem in the winter. In addition to this, the optimal glaze for the climate shell had to be determined and what type of lighting technology would be the most viable. The hybrid greenhouse is a gableroof greenhouse with insulated north, west and east walls designed for microgreen cultivation, Lactuca Sativa. The interesting part of the greenhouse is that it has a retractable insulation cover, of mineral wool, inside of the climate shell. This was meant to heavily insulate the greenhouse during the winter seasons, though it would not let any sunlight in. This meant that the hybrid greenhouse must rely on artificial lighting in the winter but will get a reduced heating demand. When the outdoor temperature rises and the sun becomes more visible,the cover can be retracted to utilize sunlight for heating and photosynthesis. The cost between heating and electricity usage and the profits from the amount of yield will therefore vary depending on how long the coveris opened or closed and an optimal cost solution should be found somewhere within that variation. The model was created using Simulink version 10.6, which could simulate the heat demand, the humidity level, CO2-concentration, and the yield of the greenhouse.

    The models heat demand and yield was validated againsta greenhouse in Nikkala, Sweden, owned by Norrskenstomater. The model produced a standard deviation of 24.6 MWh over three months but it overestimated the yearly yield of Norrskenstomater with about 40%. To make the sure the hybrid greenhouse performed effectively, the amount of leakage must be minimized, as this has a significant impact on the heat demand. The hybrid greenhouse needs lighting alternatives with substantial active cooling (90% of the lamps input power), such as light emitting diodes. High pressure sodium lamps produce too much heat and can not be used at all. For yearly simulations, the cover was set to close for certain amounts of months during the year. The highest yearly profit, highest net present value (4.8 MSEK) and lowest payback time (3.5 years) could be achieved if the cover were closed between October and March. The best glazing material in terms of economic performance was 4 mm glass followed by 16 mm plastic panels in acrylic. The hybrid greenhouse could even outperform a greenhouse that did not cultivate during the winter. The hybrid greenhouse seems to get rid of the negative impacts of winter cultivation and is therefore considereda viable alternative as a cultivation system for subarctic climates.

    Reflection on reflection in action: A case study of growers conception of irrigation strategies in pot plant production2009In: AI & Society: The Journal of Human-Centred Systems and Machine Intelligence, ISSN 0951-5666, E-ISSN 1435-5655, Vol. 23, no 4, p. 545-558Article in journal (Refereed)
    Abstract [en]

    A case study of growers conception of irrigation strategies indicates that pot plant growers in Scandinavia base their management approaches on experientially based art. The study also indicates that there is a gap between experientially based art and available greenhouse technology. In order to standardize production and produce quality, both the grower's experience and available technology should be taken into account. In order to achieve this, the present study proposes to arrange reflection on reflection in action with a group of growers by means of the dialogue seminar method. The concept of reflection on reflection in action is novel to horticultural practice. Therefore, we suggest future inter- and multidisciplinary research within this domain.

    Prospects of dialogue-inspired methods as tools for knowledge transfer: Technology for sustainable horticulture meets experiential knowledge communities2009In: Acta Horticulturae, International Society for Horticultural Science , 2009, p. 27-32Chapter in book (Refereed)
    Abstract [en]

    Horticultural production systems have a large environmental impact. Legislation, ordinances and quality assurance systems provide guidelines for implementing sustainable production technologies in horticulture at a higher level. Horticultural research has compiled solutions to improve sustainable production. Despite of regulations, hands-on information, solid scientific data on sustainable strategies for horticulture and a general environmental awareness, there is reluctance in considering sustainable technology and reorganizing horticultural production lines. Knowledge within commercial horticulture is situated knowledge; this means experience consolidated within the branch is a precondition for application. However, knowledge on sustainable technology follows the tradition of natural sciences and technology. Another crucial aspect concerns the path from understanding sustainable technology to putting it into action. Reflection on reflection in action as an activity aims at producing a good verbal description of reflection in action, which can be shared with other people. While reflection in or on action is primarily private the notion of reflection on reflection in action is tied to the fact that learning and experience exchange are social activities that proceed in different communities of practice. Dialogue-inspired methods may act as a tool. In the present paper we discuss the dialogue seminar and Socratic dialog methods to bridge the gap between scientific and technological progress in horticulture and horticultural practice to be employed in horticultural extension.

    Vattenrening för ökad hygien vid odling av frilandsgrönsaker och bär2017Other (Other (popular science, discussion, etc.))
    Abstract [sv]

    Under senare år har ett flertal utbrottmed magsjuka kopplats till konsumtionav grönsaker, frukt och bär. Sjukdomsframkallandebakterier och virus, såsomnorovirus, Salmonella, toxinproducerandeE. coli, Campylobacter och Listeria. kanspridas från bevattningsvatten via grö-dan till människor och orsaka sjukdom.Smittat bevattningsvatten kan därförförorena frilandsproducerade grönsakeroch bär. Det är alltås viktigt att hakontroll på bevattningsvattnets kvalitet.Dessutom är det viktigt att känna tillvilken typ av kultur som vattnet skaanvändas till, eftersom risken för vidaresmitta till människor varierar mellanolika typer av kulturer. T.ex. är det störrerisk att använda kontaminerat vatten tillkulturer som äts råa utan uppvärmninghos livsmedelsproducenten eller konsument,eftersom det då inte finns nå-gon möjlighet att avdöda de oönskademikroorganismerna i ett efterföljandesteg. Genom rätt hantering och adekvatbehandling av bevattningsvattnetkan dess hygieniska kvalitet förbättras.Ibland finns det möjlighet för odlarenatt byta vattenkälla, men då detta inte ärpraktiskt möjligt kan det kontamineradevattnet renas innan bevattning. I dettafaktablad beskrivs två grundläggandetekniker för rening av bevattningsvattenvid frilandsproduktion, nämligen fotokemi(fotokatalys, UV) och filtrering(mekanisk filtrering, långsamfiltrering).Dessa används för att minska risken försmittspridning med bevattningsvattnet.

    Abstract [sv]

    Ruiner behöver träd, doftande örter och blommor för att bli minnesvärda. Det förstärker den historiska upplevelsen och ruinens eget förgänglighetsuttryck. Hur man närmar sig en ruin är också betydelsefullt. Kanske är den strapatsrika vandringen till målet viktigare än att parkeringsplatsen ligger nära. I det successiva närmandet finns många upptäckter att göra om man använder alla sina sinnen.

    Negative emissions at negative cost-an opportunity for a scalable niche2022In: Frontiers in Energy Research, E-ISSN 2296-598X, Vol. 10, article id 806435Article in journal (Refereed)
    Abstract [en]

    In the face of the rapidly dwindling carbon budgets, negative emission technologies are widely suggested as required to stabilize the Earth's climate. However, finding cost-effective, socially acceptable, and politically achievable means to enable such technologies remains a challenge. We propose solutions based on negative emission technologies to facilitate wealth creation for the stakeholders while helping to mitigate climate change. This paper comes up with suggestions and guidelines on significantly increasing carbon sequestration in coffee farms. A coffee and jackfruit agroforestry-based case study is presented along with an array of technical interventions, having a special focus on bioenergy and biochar, potentially leading to "negative emissions at negative cost. " The strategies for integrating food production with soil and water management, fuel production, adoption of renewable energy systems and timber management are outlined. The emphasis is on combining biological and engineering sciences to devise a practically viable niche that is easy to adopt, adapt and scale up for the communities and regions to achieve net negative emissions. The concerns expressed in the recent literature on the implementation of emission reduction and negative emission technologies are briefly presented. The novel opportunities to alleviate these concerns arising from our proposed interventions are then pointed out. Our analysis indicates that 1 ha coffee jackfruit-based agroforestry can additionally sequester around 10 tonnes of CO2-eq and lead to an income enhancement of up to 3,000-4,000 Euros in comparison to unshaded coffee. Finally, the global outlook for an easily adoptable nature-based approach is presented, suggesting an opportunity to implement revenue-generating negative emission technologies on a gigatonne scale. We anticipate that our approach presented in the paper results in increased attention to the development of practically viable science and technology-based interventions in order to support the speeding up of climate change mitigation efforts.

    Abstract [en]

    We are moving towards a future where an increasingly larger portion of the world’s population lives in urban areas, which entails a number of challenges that will need to be addressed. By the year 2050, it is expected that nearly 70% of the population will reside in urban areas, compared to 30% in 1950. This increase means that green spaces will be replaced by housing, leading to smaller-sized homes and rising prices. At the same time, the negative effects of not being surrounded by plants and nature are becoming more significant and evident.This project in Technical Design at Luleå University of Technology aims to explore the possibilities of mitigating these negative effects by creating sustainable opportunities for individuals to cultivate plants at home. By examining the needs of the target audience and employing a user-centered design process, a variety of creative design methods have been utilized to explore solutions and possibilities. Through an iterative process, a range of different solutions have been developed and evaluated by users.This has resulted in a concept that allows for home cultivation using vertical hydroponic farming,

    Abstract [en]

    Abstract

    The research in the interdisciplinary field of natural-human-health-design has in recent decades gainedmomentum and led to new or new-old ways of thinking and acting in terms of planning and design of outdoorenvironments with the aim of health promotion. Concrete concept models and design guides have begun toemerge as a result of this research.The purpose of this work is to use these guides to develop a design proposal for a supposed health garden,with Wij Trädgårdar in Ockelbo as a base. This has been done in the form of a process description. The targetgroup for the design proposal is long-term unemployed and people who have come to Sweden as refugees.Since the specific design recommendations could not be found for the selected target group, the main materialwas general guidelines for health gardens in combination with guidelines for health gardens directed to targetgroups with stress-related problems, which is a broad target group for which there are relatively much currentresearch.The result is a process description of the progression towards a sketch on a health garden, designed for aspecific spot on Wij Trädgårdar, but available for use in other locations, provided adjustments is made to thespecific location. The sketch is supplemented with plant suggestions to different parts of the garden. A sketchof an alternative proposal is included as a smaller, faster and cheaper version of the main design proposal.

    Kan växter lindra klimakteriebesvär?: Behandling av vasomotoriska symptom med hjälp av örtmedicin2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to investigate the use of herbal medicine for vasomotor symptoms during menopause. The questions posed were which herbs that were used, what parts of the herbs that were used, and how the plant parts were prepared and utilized. The last question covered how much the plants alleviated the vasomotor symptoms.

    A review of the scientific literature was carried out. In the articles, 20 herbs and plants were used, but only five of them were said to relieve the vasomotor symptoms. The five plants were Actaea racemosa, Angelica sinensis, Ginkgo biloba, Glycine sp. and Pimpinella anisum.  The most commonly used parts of the herbs were the roots, often through extracts that were processed in order to increase the concentration and to transform the plant parts into powder. The powder was then for the most part transformed to tablets and capsules. Sometimes, information was missing, such as the scientific names of the plants, what parts of the plants that were used and how the herbs were prepared and utilized.

    On average, the herbs alleviated the vasomotor symptoms by 60 %. Most of the herbs appeared to relieve mild symptoms more than they alleviated strong symptoms. An exception was P. anisum, which decreased both the amount of and the strength of the flushes by 74 %.

    This literature study shows that there are plants that influence the vasomotor symptoms in a positive direction. At the same time, it shows that the information in the articles is sometimes incomplete and that the scientists do not always study if the herbs can give side effects.

    Herbal medicine could be an alternative for women who, for different reasons, cannot or do not want to take synthetic hormones or other pharmacological medicines. However, in order to make herbal medicine part of the treatment offered by public health care, longitudinal studies that also investigate possible side effects or risks are needed for securing the effect of the herbs on the human body.

    Mechanical Performances of Isolated Cuticles Along Tomato Fruit Growth and Ripening2021In: Frontiers in Plant Science, E-ISSN 1664-462X, Vol. 12, article id 787839Article in journal (Refereed)
    Abstract [en]

    The cuticle is the most external layer that protects fruits from the environment and constitutes the first shield against physical impacts. The preservation of its mechanical integrity is essential to avoid the access to epidermal cell walls and to prevent mass loss and damage that affect the commercial quality of fruits. The rheology of the cuticle is also very important to respond to the size modification along fruit growth and to regulate the diffusion of molecules from and toward the atmosphere. The mechanical performance of cuticles is regulated by the amount and assembly of its components (mainly cutin, polysaccharides, and waxes). In tomato fruit cuticles, phenolics, a minor cuticle component, have been found to have a strong influence on their mechanical behavior. To fully characterize the biomechanics of tomato fruit cuticle, transient creep, uniaxial tests, and multi strain dynamic mechanical analysis (DMA) measurements have been carried out. Two well-differentiated stages have been identified. At early stages of growth, characterized by a low phenolic content, the cuticle displays a soft elastic behavior. Upon increased phenolic accumulation during ripening, a progressive stiffening is observed. The increment of viscoelasticity in ripe fruit cuticles has also been associated with the presence of these compounds. The transition from the soft elastic to the more rigid viscoelastic regime can be explained by the cooperative association of phenolics with both the cutin and the polysaccharide fractions.

    Tångodlad potatis- nyttigt eller skadligt?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The nutrition bound in macroalgae, also known as seaweed, contains high amounts of all the nutrients, micronutrients, vitamins and plant hormones, necessary for plants, animals and humans. Totally for free it is floating in the oceans around the world and has been harvested and used by people for thousands of years. A problem that has arisen in the wake of Industrialism during the past 200 years is that human beings spread non-desirable substancesto air, water and soil, for example heavy metals. Macroalgae accumulate the heavy metals, which may become a problem if we want to eat seaweed or use it to grow plants in.  In a growth trial using macroalgal compost made from Fucus radicans collected from the Baltic Sea, the uptake heavy metals in the edible tubers of potatoes of the cultivar ‘Cherie’ was investigated. The following heavy metals were analyzed: lead(Pb), cadmium (Cd), mercury (Hg), arsenic (As) and copper (Cu). There were no differences in the uptake of heavy metal between potatoes grown in macroalgal compost and soil, but the potato tubers from both cultivations contained concentrations of Cd and As higher than those normally found in Swedish potatoes. The concentrations are, however, much lower than the limits set by EFSA. The macroalgal compost and the soil used in the experiment were also analyzed for heavy metal content. The Cd concentration in the compost exceeded the limit for Swedish compost. However, the high levels of Cd in the compost were not reflected in the Cd content of the potato tubers. Soil conductivity and pH values were also investigated. The high conductivityof the macroalgal compost was probably due to insufficient rinsing of the macroalgae, and thus it was not ideal for use in crop cultivation. In spite of this, the crop yield was good. In conclusion, macroalgal compost can be recommended as a cultivation substrate for potatoes.

    Effects of plant competition and herbivore density on the development of the turnip root fly (Delia floralis) in an intercropping system2009In: Arthropod-plant interactions, ISSN 1872-8855, Vol. 3, p. 55-62Article in journal (Refereed)
    Abstract [en]

    In this study, interactive effects of plant competition and herbivory on plant quality and herbivore development were examined in a greenhouse experiment where cabbage plants [Brassica oleracea L. var. capitata (Brassicaceae)] were intercropped with red clover [Trifolium pratense L. (Fabaceae)]. Cabbages were grown with two red clover densities and attack rates by the root feeding herbivore the turnip root fly, Delia floralis Fall. (Diptera: Anthomyiidae). Above ground and below ground cabbage biomass was reduced through intercropping and larval damage. Intercropping also resulted in lower nitrogen and higher carbon root levels compared with levels in the roots of monocultured cabbage. Furthermore, both root nitrogen and carbon levels increased with herbivory. Root neutral detergent fibre (NDF) and lignin content increased in response to both increased plant competition and higher egg densities. For lignin, an interaction effect was observed in the form of elevated levels in intercropped plants subjected to larval damage, while levels in roots of monocultured cabbage remained unchanged. The quality changes brought about by clover competition affected D. floralis development negatively, which resulted in reduced pupal weight. In addition, increased egg density also decreased larval growth. The effects on the development of D. floralis in relation to host plant quality are discussed.

    Biokol i stadsträdens växtbäddar: med fokus på Stockholm stad2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The ground is an important factor to consider in today's tough climate for our urban trees. Especially for the trees that shall live in the most vulnerable parts of the city, such as the square, along heavily trafficked roads or surrounded by only paved surfaces. One solution is structured soils which is used in many cities in Sweden but also in other countries. An interesting new development of structured soils where AMA-soil has been replaced with biochar is now being tested in a project in Stockholm. The focus in this paper will therefore be on how biochar is used practically in the tree plant beds and the effects this has on the trees' development.

     

    The purpose of this paper is to get an insight on how biochar in urban tree plant beds are used with examples from Stockholm Biochar Project. And also to examine the parameters used to measure the effect biochar have on tree growth, and to assess the impact of biochar has on the trees.

     

    The work of this paper was carried out as an interview study and was then also combined with research in scientific books and articles. The interviewee is active in the area and works as a tree specialist at the traffic office,Stockholm city and complicit in Stockholm Biochar Project. Researched have been done in various databases where the keywords biokol, biochar, terra preta, urban city trees and tree inventory have been used.

     

    The construction of the plant bed with biochar in Stockholm city has proved to be similar to the old model, but it differs in that the AMA-soil has been exchanged for biochar and also in that the dimensions of the macadam instructured soil is changed.

     

    The parameters used in the Stockholm city to measure tree growth are stem circumference. But there are also other parameters that could be used to measure growth and these could also be applied to assess effect of the biochar on the tree.

     

    In a comparison of tree growth, where tree of the same species had grown in similar conditions but in three different types of plant beds, the results showed that the trees planted in biochar did not have the best growth.

    Sorter av köksväxter: Svenska priskuranter från 1800-talet till 19302015Book (Other (popular science, discussion, etc.))
    Abstract [sv]

    Det finns idag ingen fullständig förteckning över sorter av köksväxter som odlats i Sverige samt vilka sorter som kan räknas som svenska. För att få svar på detta genomfördes 2012 och 2014 ett projekt med mål att få en förteckning på sorter av köksväxter som odlats i Sverige. Avsikter var också att ta reda på när de började säljas och när de försvann från marknadensamt om dessa sorter idag går att få tag på i genbank eller hos odlare. Beskrivning av sorterna var också önskvärt att få fram för att kunna skilja sorterna åt och, ifall de finns kvar, kunna utnyttja deras egenskaper, både i sin nuvarande form och i en framtida förädling. Tiden begränsades från 1800-talet fram till 1900-talets början. Den ursprungliga målsättningen att få en fullständig förteckning på sorter av köksväxter som odlats i Sverige från 1800-talet och framåt visade sig vara omöjligt. Det blev en förteckning (bilaga 2) men den har flera brister. Omfattningen av materialet bidrog till detta men ännu mer att det inte fanns en standardisering för sortnamn och sortbegrepp. Tonvikten i undersökningen skulle ligga på svenska sorter, vilket var ännu svårare eftersom det inte går att avgöra när en sort är svensk. Tydligt svenska sortnamn saknades nästan helt på 1800-talet men blev mer vanligt i början på 1900-talet. Det går också att konstatera att det var förvånansvärt många sorter som fortsätter att hänga med från mitten av 1800-talet till 1930.

    Improving water use efficiency in vertical farming: Effects of growing systems, far-red radiation and planting density on lettuce cultivation2023In: Agricultural Water Management, ISSN 0378-3774, E-ISSN 1873-2283, Vol. 285, p. 108365-108365, article id 108365Article in journal (Refereed)
    Abstract [en]

    Vertical farms (VFs) are innovative urban production facilities consisting of multi-level indoor systems equipped with artificial lighting in which all the environmental conditions are controlled independently from the external climate. VFs are generally provided with a closed loop fertigation system to optimize the use of water and nutrients. The objective of this study, performed within an experimental VF at the University of Bologna, was to quantify the water use efficiency (WUE, ratio between plant fresh weight and the volume of water used) for a lettuce (Lactuca sativa L.) growth cycle obtained in two different growing systems: an ebb-and-flow substrate culture and a high pressure aeroponic system.

    Considering the total water consumed (water used for irrigation and climate management), WUE of ebb-and-flow and aeroponics was 28.1 and 52.9 g L−1 H2O, respectively. During the growing cycle, the contribution generated by the recovery of internal air moisture from the heating, ventilation and air conditioning (HVAC) system, was quantified. Indeed, by recovering water from the dehumidifier, water use decreases dramatically (by 67 %), while WUE increased by 206 %. Further improvement of WUE in the ebb-and-flow system was obtained through ameliorated crop management strategies, in particular, by increasing planting densities (e.g., 153, 270 and 733 plants m−2) and by optimizing the light spectrum used for plant growth (e.g., adjusting the amount of far-red radiation in the spectrum). Strategies for efficient use of water in high-tech urban indoor growing systems are therefore proposed.

    Abstract [en]

    The food value chain system in Sweden is well established making it hard for small companies to develop new products and even harder to create new food supply systems Obstacles could lay at the beginning of the chain (food production or processing), at the end (marketing, consumer) or could even be related to the legislative regulation framing the food supply chain. Smaller actors often lack resources and networks to develop their sector. However, their degree of creativity, innovativeness, and engagement is high, and their energy is needed in the development of new sustainable food value chains.

    The aim of this project was to develop and apply a methodology for evaluating food value chains, focusing on profitable small-scale production systems in Sweden that show potential for fast development of new products that quickly reach the market. The work also included identifying Swedish raw food materials with growth potential and to identify how they could come into greater demand. Ten food value chains with high development potential in Sweden and for export were mapped and the main bottlenecks briefly described. Three food chains where selected based on a potential-difficulty-benefit matrix. The three selected food value chains were: (i) Hops, (ii) Swedish forest berries, and (iii) Land-based fish farming. These three food value chains where further studied looking at the whole value chain, from production to end consumer. Through literature review and contacts with relevant stakeholders (telephone interview, face-to-face interview, or workshop) the bottlenecks were clarified and potential solutions for increased demand where identified.

    Swedish hops production is carried out by passionate and engaged smaller actors, mostly on a hobby level, and the hops is used as an ingredient for beer. Germany and the USA produce about 75% of the worldwide production These hops varieties are not adapted to the Swedish climate and therefore result in a low volume and poor quality. However, domestic varieties have been grown in the past giving better yield under Swedish climate conditions. More work is needed to characterize the quality of Swedish hops. At the present time, knowledge about the characteristics of Swedish hops is low, explaining the lack of interest from brewers. In Sweden most hops are harvested by hand, making it nearly impossible to be profitable on the market. The mechanization of the harvesting step is necessary to move Swedish hops from a hobby to a commercial activity. No solutions are available on the Swedish market, RISE together with SLU is looking to develop a hops harvester fulfilling Swedish and EU regulations and adapted to small scale cultivation. At the end of the value chain, innovative products could increase the need for Swedish hops, for example by developing beers brewed with fresh hops. Moreover, hops have antiseptic characteristics and could potentially be used in other food products than beer.

    Only about four percent of the berries that are produced by the Swedish forests every year are picked. The largest volumes picked are for bilberry (Swedish: blåbär), lingonberry, and cloudberry and most of them are washed and frozen in Sweden. Processing of berries, however, has to a large extent moved out of the country while the products produced for the Swedish market are quite traditional, low-processed foods such as jams, juices and dessert soups. The majority of the Swedish berries mainly bilberries due to their nutritional content are exported and are further processed into value added powders or extracts in Asia and Europe. In Sweden this kind of value chain is under developed largely due to knowledge barriers and to the currently very traditional market. However, there is a great consumer interest in berries and they have a perceived healthiness also in Sweden. Consumers are also increasingly aware of the origin of berries used as ingredients in products such as jams, purees and juice, as well as in health food products. To fill this gap between consumer interest/demand and raw materials available new businesses can be developed. To facilitate such development there is a need for knowledge generation and transfer along the whole value chain (picking, processing, product development and consumer studies), which can be generated by starting up new innovation and research projects. It is also of importance to facilitate networking, for example in the ‘berry network’ (coordinated by RISE), as the creation of a new value chain will require different businesses to cooperate. Also, product development projects will need support for testing, pilot production, and possibly in finding investment funding for new equipment.

    Land-based fish farming is small in comparison to traditional fish farming in Sweden, but several actors see a great potential in this system which has a lower impact on the environment compared to conventional fish farms. For instance, the Swedish farmer federation (LRF) has invested in a land-based fish farm recently. As in other EU-countries, the number of active farms in Sweden is decreasing and some see the potential to recycle unused animal stables into fish farms. A major bottleneck for land-based fish farming is current legislation as it is based on conventional fish farming and therefore does not consider the environmental benefits of land-based systems. Knowledge should be spread to relevant authorities and policy makers to open a dialog and facilitate the development of a relevant regulatory framework. Regarding the production phase, access to sustainably produced feed and technical competence are lacking. Moreover, as the technology is costly learning through trial and error would not be recommended. A testbed dedicated to land-based fish farming could support companies who wish to try modifications to their system. Furthermore, smaller producers have difficulties in finding processing solutions for their products; e.g. slaughterhouses and conditioning. Two potential solutions would be to develop a land-based fish farm cooperative and/or mobile systems that could take care of smaller productions. Finally, the competition on the market is tough as land-based fishes are competing with large-scale conventional fish farms from Norway and Asia. To overcome this bottleneck, the sector could develop its own certification as well as increasing the consumers awareness and knowledge.

    Some conclusions could be applied to all the studied food chains. For instance, each value chain can be seen as a puzzle with many pieces. In order to develop new food value chains many separate pieces need to fall into place. Therefore, it is necessary to increase collaboration between stakeholders but also to have a stakeholder driven coordination of this collaboration. The stakeholders within the developing value chains often do not have all the resources to carry out this task, especially if they are small businesses. The development of cooperatives also seems to be a solution to overcome bottlenecks in the studied food chains. Likewise, logistics in the developing value chains have a great margin for improvement. Furthermore, this project focused on value chains where food commodities are the end product but investigating the potential for non-food uses would also be of interest.

    The method used in this project can be replicated to other value chains with potential of development. It would help the users to get a holistic view of the current bottlenecks and facilitate contact between stakeholders. The list of bottlenecks can be followed up and used as an indicator to evaluate if the value chain in moving forward.

    Natural Ecosystem Surrounding a Conventional Banana Crop Improves Plant Health and Fruit Quality2018In: Frontiers in Plant Science, E-ISSN 1664-462X, Vol. 9, article id 759Article in journal (Refereed)
    Abstract [en]

    Natural ecosystems near agricultural landscapes may provide rich environments for growing crops. However, the effect of a natural ecosystem on crop health and fruit quality is poorly understood. In the present study, it was investigated whether the presence of a natural ecosystem surrounding a crop area influences banana plant health and fruit postharvest behavior. Plants from two conventional banana crop areas with identical planting time and cultural practices were used; the only difference between banana crop areas is that one area was surrounded by a natural forest (Atlantic forest) fragment (Near-NF), while the other area was inserted at the center of a conventional banana crop (Distant-NF). Results showed that bananas harvested from Near-NF showed higher greenlife and a more homogeneous profile during ripening compared to fruits harvested from Distant-NF. Differences in quality parameters including greenlife, carbohydrate profile, and pulp firmness between fruits harvested from Near-NF and Distant-NF are explained, at least partly, by differences in the balance of plant growth regulators (indole-3-acetic acid and abscisic acid) in bananas during ripening. Furthermore, plants from Near-NF showed a lower severity index of black leaf streak disease (BLSD) and higher levels of phenolic compounds in leaves compared to plants from Distant-NF. Together, the results provide additional evidence on how the maintenance of natural ecosystems near conventional crop areas could be a promising tool to improve plant health and fruit quality.

    From bean collection to seed bank: transformations in heirloom vegetable conservation, 1970–19852019In: BJHS Themes, ISSN 2058-850X, 2056-354X, Vol. 4, p. 149-167Article in journal (Refereed)
    Abstract [en]

    In 1975, the Missouri homesteaders Kent and Diane Ott Whealy launched True Seed Exchange (later Seed Savers Exchange), a network of ‘serious gardeners’ interested in growing and conserving heirloom and other hard-to-find plant varieties, especially vegetables. In its earliest years, the organization pursued its conservation mission through member-led exchange and cultivation, seeing members’ gardens and seed collections as the best means of ensuring that heirloom varieties remained both extant and available to growers. Beginning in 1981, however, Kent Whealy began to develop a central seed repository. As I discuss in this paper, the development of this central collection was motivated in part by concerns about the precariousness of very large individual collections, the maintenance of which was too demanding to entrust to most growers. Although state-run institutions were better positioned to take on large collections, they were nonetheless unsuitable stewards because they placed limits on access. For seed savers, loss of access to varieties via their accession into a state collection could be as much an ending for treasured collections as total physical loss, as it did not necessarily enable continued cultivation. As I show here, these imagined endings inspired the adoption of a new set of conservation practices that replicated those seen in the formal genetic conservation sector, including seed banking, cold storage and safety duplication.

    Byta lind mot lind: En studie om trädbyten vid historiska anläggningar2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this paper is to examine how a tree replacement is carried out in a place that is protected as a cultural heritage. The places described are the Baroque garden in Uppsala Botanical Gardens and the baroque garden in the palace garden at Drottningholm. Both gardens are owned by the state and managed by the National Property Board. The National Heritage Board has overall responsibility that the facilities are not distorted. The Botanical Garden in Uppsala belongs to Uppsala University and is managed by the University. The gardens have a high historical value that make them worthy of protection. Because of this there are restrictions and regulations that dictate how the locations should be maintained and administered. The thesis is based on interviews with the project manager for both of the tree-replacements and the garden Director and 1st gardener at the Botanical Garden in Uppsala. The old lime trees at Drottningholm were planted in the late 1600s and early 1700s and was largely dutch lime, Tilia x europaea 'Pallida', imported from Holland. The old lime trees in the botanical garden was planted in the 1970s, when the garden was restored under the direction of Walter Bauer. The tree replacement at Drottningholm was conducted between 1997–2011 in five stages and the restoration in the Botanical Garden is carried out in autumn 2016 and is expected to be completed in June 2017. Both the construction work and a five-year warranty maintenance is performed under contract. The paper describes what influences the choice of the trees at the facilities. There have been studies to determine the species and varieties of the original lime trees in the avenues at Drottningholm. The new lime trees planted there and those that will be planted in the spring of 2017 in the Botanical Garden, are of the same type as the original lime trees at Drottningholm. A large number of measures have been carried out at the installation and maintenance of the trees to ensure that they establish themselves properly and develop well.

    Hälsoparken Fjärran Höjder i Gävle: Sveriges mest uthålliga och integrativmedicinska hälsoanläggning : rapport avseende: förstudie av integrativ hälsomottagning vid Fjärran Höjder : ett projekt finansierat av Gävle Kommun och Region Gävleborg2009Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    Projektet ”Förstudie av integrativ hälsomottagning vid Fjärran Höjder” har genomförts under hösten 2008. Arbetet har varit inriktat på att följa och genomföra den projektbeskrivning som gavs i samband med ansökan om medel. Till stöd i arbetet har projektledaren haft Arbetsgruppen för en integrativ hälsomottagning vid Fjärran Höjder, vilken sammanträtt fyra gånger under projekttiden. Flera av medlemmarna i arbetsgruppen har också deltagit i studieresorna och föreläsningsserien som anordnats. I syfte att undersöka förutsättningarna för en etablering av hälsomottagningen har en attitydundersökning genomförts bland ett antal utvalda vårdtagare och vårdgivare, politiker, anställda och arbetsgivare, samt besökare vid Fjärran Höjder. Undersökningen visar i korthet att det finns ett stöd för anläggandet av en hälsopark vid Fjärran Höjder. De studieresor och den föreläsningsserie med avslutande dialogmöte som genomförts, har syftat till att förankra idén hos de hälsoaktörer som kan tänkas bli involverade i projektet framöver. Arbetet i arbetsgruppen har mycket handlat om att arbeta fram en projektidé, ett program eller en projektplan för den föreslagna integrativa hälsomottagningen. En viktig del i en sådan plan har varit att sätta in mottagningen i ett större sammanhang, det vi nu vill kalla Hälsoparken Fjärran Höjder. Hälsomottagningen skulle då ingå i en större helhet, en miljö vars samtliga delar syftar till att främja hälsan hos parkens besökare. Visioner och mål för hälsoparken har arbetats fram, liksom ett preliminärt förslag till utformning av hälsoparken och verksamhet där vid. I fortsättningen av projektet avses att söka medel från Osherstiftelsen och i det fall projektet får fortsatt stöd från Gävle Kommun och Region Gävleborg även EU-medel, eftersom det krävs egenfinansiering vid sådana ansökningar. Förslag till hur projektet kan vidareutvecklas lämnas i rapportens avslutande del.

    Traditional uses and practices of edible cultivated Allium species (fam. Amaryllidaceae) in Sweden2022In: Journal of Ethnobiology and Ethnomedicine, E-ISSN 1746-4269, Vol. 18, article id 14Article in journal (Refereed)
    Abstract [en]

    Background: While the utilitarian crops grown in vicarage gardens in pre-industrial Sweden have been fairly well documented, our knowledge of plants cultivated for food among the peasants and crofters is limited. Nevertheless, garden vegetables and herbs played a much more important role in the diet of the rural population from a nutritional point of view than, say, wild plants, at least in the southern part of the country. This study aims to explore the importance of edible cultivated onions, Allium, and their various cultivars and old landraces that were once-and in some cases still are-grown in home gardens.

    Methods: This study is based on documentation collected from national surveys carried out by the Swedish National Programme for Diversity of Cultivated Plants (POM), and from an intense search for references to the cultivation and use of carious onions in the historic garden literature, herbals and ethnographic records found in responses to folklife questionnaires.

    Results: The rural population in pre-industrial Sweden cultivated various kinds of bulb onions. They are known under various folk names, although their taxonomic affiliation has been unclear. Many folk taxa have been classified and named by their use, while other names refer to the practices associated with the cultivation system. These onions were often described as especially well suited for storage over winter. Onions have had a wide range of uses in Sweden. In some parts of Sweden, onions were eaten during church service in order to keep the churchgoers awake. Several types of onion have commonly been used as condiments in pickled herring dishes, spreads, sauces, foods made of blood and offal, dumplings, meat dishes and soups. Garlic was used for medicinal and magical purposes, as well as for ethnoveterinary medicine. Onion skins have traditionally been used for dyeing eggs at Easter.

    Conclusion: Genetic diversity of vegetables and garden crops represents a critical resource to achieve and maintain global food security. Therefore, ethnobiologists studying agricultural societies should place more focus on old landraces, cultivars and cultivation practices in order to understand the importance of garden crops for a society. They are an important element of sustainability.

    Attitudes towards plants - exploring the role of plants' ecosystem services2024In: Journal of Biological Education, ISSN 0021-9266, E-ISSN 2157-6009Article in journal (Refereed)
    Abstract [en]

    With biodiversity loss as one of today's most pressing global problems, it is crucial to raise public recognition of this crisis and promote acceptance of conservation efforts. Plants, which typically struggle with low awareness ('plant blindness') and less emotional connection than animals with humans, are facing a special challenge. Promoting positive attitudes towards, and interest in, plants might provide the key to resolve this discrepancy. This study aims to differentiate attitudes and interest within the plant awareness framework while at the same time identify criteria for developing positive attitudes and interest towards plants in students. In a mixed-method approach, a questionnaire with closed and open items on attitudes and interest was developed and administered online to 179 students aged 9-19. Quantitative as well as qualitative results show that 'attitudes towards plants' can be differentiated from 'interest in plants'. Attitudes towards plants were positive, whereas interest in plants was rather low, with cultural and regulating ecosystem services acting as primary reasons for students' positive attitudes. These two components can be easily incorporated in botany teaching in order to promote plant awareness and increase knowledge about their crucial role in ecosystems and global climate, thus raising acceptance for conservation.

    Hållbar skolträdgård: Ett designförslag med skogsträdgården som förebild2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Growing is a creative activity in lower school subject matter. It is an outdoor activity that creates movement. Gardening activities give favorable effects for the social teamwork in studentgroups and cultivation is a way to increase students' awareness of our food production. This argument exists in earlier studies that it is significant when school staff have motivated reasons to create school gardens. Of course, school gardens have always created problems. To get enough resources for management and lesson planning and to handle summer supervision presents in modern times as the largest obstacles for growing activities to work. Against this background, the purpose of this thesis is to find a way forward for gardening as a school activity that increases students' consciousness of sustainable food production. 

    Forest gardening is a cultivation model within the Agro Forestry movement. Using literature study as a methodology, it is found that forest gardening principles can be applied to school gardening to solve the identified isues with cultivation in primary schools. 

    Regarding forest gardening principles, one can create a cultivation that occupies a small  area and recieves the ideal microclimate with an array of plants with different hights. This cultivation model lowers the work time required and the need for summer supervision. In addition, this cultivation gives the ecosystem increased biodiversity and carbon storage. Another advantage with this cultivation model is that through plant selection, one can control harvest times to spring and autumn, when students are in school. However, it appears that this cultivation model is knowledge- intensive during the construction phase and that it is a good idea to get outside help from an expert, for example, a gardener with expertise in forest gardening.

    A design proposal for lower school grades is also included, with a plant list and design plan that can be adapted and suited to schools.

    Odling i sand: En undersökning av markfysikaliska egenskaper hos sandjordar och om anläggning av odlingsbäddar2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med examensarbetet är att försöka förklara de markfysikaliska egenskaperna hos en sandjord och hur det med hjälp av olika kornstorlek är möjligt att uppnå dessa egenskaper i en odlingsbädd. Sandjordar kan anses som problematiska då de har svårare att behålla fukten i jorden och dessutom är näringsfattiga. Detta gäller såväl artificiella som naturliga sandjordar. Vattnet kan beroende på kornstorlek och tillförsel av mull ha lättare eller svårare att förflytta sig i marken. Detta kan vara avgörande för hur en växt överlever och trivs i en sådan miljö. Den värmehållande förmågan varierar på grund av sandjordens kornstorlek och inblandning av mull. En sandbädd blir varm tidigare på våren än en bädd av mull och därför kan odlingssäsongen förlängas. En planta som är härdig t ex, till zon II, har om den står i sandjord större chans att klara vinterhalvåret i en högre belägen zon, än om den är planterad i mulljord men jordens fukthalt har också en avgörande betydelse. Det är viktigt att sandjorden har en bra sammansättning – är det för stor andel mycket små partiklar dräneras inte överflödigt vatten bort och vattnet blir stående i sandbädden - vilket medför ökad risk att plantan fryser under vintern. Syftet med uppsatsen har också varit att undersöka hur en odlingsbädd av sandjord kan anläggas. Under uppbyggnaden av stenpartiet har jag kunnat se med vilka medel det går att ändra förutsättningarna i en sandbädd så att växter som inte är helt härdiga i vårt klimat eller som kräver speciella miljöer ändå kan överleva och trivas i vår del av världen. Studien av de markfysikaliska egenskaperna hos sandjordar har hjälpt till att förklara hur de sandbäddar som anlagts fungerar. Under arbetets gång har det även framkommit att de metoder som studerats inte kan användas överallt och att det finns flera problem med sandjordar. De är näringsfattiga och när näring sprids ut kan den på grund av sandjordens dåliga förmåga att behålla näring, orsaka näringsläckage i närliggande vattendrag.

    Pilodling till användning inom trädgård och hantverk: med tonvikt på zon 52013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med det här examensarbetet är att undersöka hur pil, eller mer specifikt, sorter inom släktet Salix sp. odlas för användning inom hantverk och trädgård. Bland dessa sorter kan nämnas korgvide (Salix viminalis). Denna typ av odling är småskalig och syftet är att få material till flätning av exempelvis korgar eller grövre arbeten som hägn och staket i trädgård. Materialet som används är vanligen ettåriga skott av odlade pilsorter som skördas när plantan är i vintervila. Därefter torkas skotten i ca 6 månader för att sedan blötläggas innan flätningen påbörjas. Blötläggningen gör pilskotten mjuka och böjliga. Pil kan även användas färsk till att skapa levande hägn genom att pilskott sticks ner i jorden och får rota sig.

     

    I detta arbete finns information om hur man kan gå tillväga för att anlägga och sköta en pilodling samt vilka markförhållanden och skötselmetoder som krävs. Fakta har samlats in genom att studera litteratur inom området, studiebesök samt mailkontakt med pilodlare. Här finns även en sammanställning av pilsorter som är härdiga att odla i zon 5.

     

    Även odling av Salix sp. för användning till biobränsle, s.k. energiskog har studerats. Anledningen till detta är att dessa odlingar, som även kallas salixodlingar, till stor del består av ovan nämnda sort korgvide (S. Viminalis). Då det har forskats mycket inom detta område har informationen varit av nytta både vad det gäller odlingsbetingelser och härdighet för Salix sp.

     

    Slutsatsen är att tillräckligt mycket information har hittats för att svara på syfte och frågeställningar. Fakta från energiskogsodlingen har inom vissa områden gett vägledning om hur skötsel av en småskalig odling kan förbättras. Även kommunikationen med verksamma pilodlare har lyft fram förslag till förbättringar.

    Life cycle assessment of a retail store aquaponic system in a cold-weather region2023In: Frontiers in Sustainability, E-ISSN 2673-4524, Vol. 3Article in journal (Refereed)
    Abstract [en]

    Alternative food production technologies are being developed to meet the global increase in population and demand for a more sustainable food supply. Aquaponics, a combined method of vegetable and fish production, is an emerging technology that is widely regarded as sustainable. Yet, there has been limited research on its environmental performance, especially at a commercial scale. In this study, life cycle analysis (LCA) was used to assess the environmental impacts of food produced by an urban commercial aquaponic system located next to a retail store in a cold-weather region (Östersund, Sweden). The functional unit (FU) used is 1 kg of fresh produce, which includes cucumber ( Cucumis sativus ), tomatoes ( Solanum Lycopersicum ), and Atlantic salmon ( Salmo salar ).

    The system boundary is set from cradle to farm or retailer's gate due to the proximity of the aquaponic system to the retail store. Results were reported employing eight environmental impact categories, including global warming potential (GWP), marine eutrophication (MEU), and cumulative energy demand (CED). According to contribution analysis, the main hotspots of the system are electricity, CO 2 enrichment, and heating. Potential areas to mitigate the impact of these parameters were highlighted in this study, including the establishment of symbiotic links to utilize urban waste and by-products. The impact per vegetable or fish produced was partitioned using energy and economic allocation and compared to other common cultivation methods. The yearly harvest from the aquaponic system was also compared to importing these food items from other European countries which showed lower annual greenhouse gas (GHG) emissions for the aquaponic system.

    Abstract [sv]

    Ordet alle betyder "gång", en yta att gå på, vilket var det centrala från början. Allen var själva mar­kytan, men ändå inramad av träd och häckar. Ytterligare ett känne­tecken på den klassiska allen är att den alltid har en målpunkt, att den leder någonstans. De tidiga svenska landsbygdsalleerna röner idag föga uppmärksamhet trots sina stora kulturvärden. Form­mässigt har de sitt ursprung i ba­rocken, men det intressanta är att de är sidoordnade och att de inte följer den räta linjen utan istället underordnar sig landskapet.

    Corporate Garden: att kommunicera varumärke eller verksamhetsområde genom den yttre miljön2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Företag och organisationer arbetar mycket med att förstärka sin position på marknaden, att leva upp till sin image och stärka sin identitet. En viktig del i arbetet handlar om att bygga ett starkt varumärke utifrån verksamhetens kärnvärden som når ut till kunderna. Det gäller att vara tydlig i sin kommunikation. Ofta kan man se en röd tråd genom ett företags grafiska profil, hur lokalerna är utformade och hur man marknadsför sig. Att inomhusmiljön speglar företagets profil och värden är lika vanligt som att ha en tydlig grafisk profil och en logotype på sitt visitkort. Däremot har de flesta företag inte någon tydlig koppling mellan miljön inomhus och den yttre miljön. Ofta är det bara företagsnamnet och loggan på husfasaden som vittnar om att företaget huserar där. Genom Corporate garden kan företag som en del i en genomtänkt företagsprofilering kommunicera sin verksamhet. Syftet med mitt examensarbete är att undersöka hur ett kommunalt tjänsteföretag kan kommunicera sitt varumärke eller sitt verksamhetsområde genom den yttre miljön.  Jag har använt mig av Sandviken Energi som studieobjekt. Till dem har jag gjort ett gestaltningsförslag, en Corporate Garden, som en del i examensarbetet. Min grundtanke har varit att kombinera funktion med kommunikation där jag använt mig av material från verksamheten som delvis kommunicerar vad företaget arbetar med. Genom att göra en processbeskrivning kommer arbetet kunna följas löpande fram till ett slutförslag. Processen omfattar informationsinsamling, analys av platsen, skissfas, skissmetod, problemlösning kring bristen på parkeringsplatser, resonemang kring idéer samt ett slutförslag som visar en utemiljö där innehållet speglar företaget och dess verksamhet.

    Mating dynamics of Scots pine in isolation tents2016In: Tree Genetics & Genomes, ISSN 1614-2942, E-ISSN 1614-2950, Vol. 12, no 6, article id 112Article in journal (Refereed)
    Abstract [en]

    Seed orchards are forest tree production populations for supplying the forest industry with consistent and abundant seed crops of superior genetic quality. However, genetic quality can be severely affected by non-random mating among parents and the occurrence of background pollination. This study analyzed mating structure and background pollination in six large isolation tents established in a clonal Scots pine seed orchard in northern Sweden. The isolation tents were intended to form a physical barrier against background pollen and induce earlier flowering relative to the surrounding trees. We scored flowering phenology inside and outside the tents and tracked airborne pollen density inside and outside the seed orchard in three consecutive pollination seasons. We genotyped 5683 offspring collected from the tents and open controls using nine microsatellite loci, and assigned paternity using simple exclusion method. We found that tent trees shed pollen and exhibited maximum female receptivity approximately 1 week earlier than trees in open control. The majority of matings in tents (78.3 %) occurred at distances within two trees apart (about 5 m). Self-fertilization was relatively high (average 21.8 %) in tents without supplemental pollination (SP), but it was substantially reduced in tents with SP (average 7.7 %). Pollen contamination was low in open controls (4.8-7.1 %), and all tents remained entirely free of foreign pollen. Our study demonstrates that tent isolation is effective in blocking pollen immigration and in manipulating flowering phenology. When complimented with supplemental pollination, it could become a useful seed orchard management practice to optimize the gain and diversity of seed orchard crops.

    Att främja social hållbarhet i gröna miljöer: En fallstudie av ett projekt i Upplands Väsby2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    In my study I have investigated how a constructed outdoor green environment can be

    used, managed and how it works. The study also investigates the concept of social

    sustainability, where, for example, civil dialogue is a method to promote this. This

    investigation mainly gives account for the inhabitants viewpoint but also a gardeners

    perspective. The study focuses on the planning process of the study object, what the

    outcome has been and how the users of the green environment, think about the result. In

    the process there has been a strong concern of involving the residents and others using

    the area. I also discuss the results concerning plantation problems, which I can see may

    influence the site identity and the quality of green areas, which in turn also can affects

    the residents relationship to it. The result also suggests that there still are possibilities

    for improvements in the dialogue and the participation of the residents of the area under

    the concept that’s been named "Dynamic habitat". The outdoor green environment can

    also further provide life quality for the inhabitants and other users, while it hopefully at

    the same time, promote the knowledge of ecosystem services.

    Relationship between anthocyanins, proanthocyanidins, and cell wall polysaccharides in grapes and red wines. A current state-of-art review2022In: Critical reviews in food science and nutrition, ISSN 1040-8398, E-ISSN 1549-7852, Vol. 62, no 28, p. 7743-Article, review/survey (Refereed)
    Abstract [en]

    Numerous research studies have evaluated factors influencing the nature and levels of phenolics and polysaccharides in food matrices. However, in grape and wines most of these works have approach these classes of compounds individually. In recent years, the number of publications interconnecting classes have increased dramatically. The present review relates the last decade’s findings on the relationship between phenolics and polysaccharides from grapes, throughout the entire winemaking process up to evaluating the impact of their relationship on the red wine sensory perception. The combination and interconnection of the most recent research studies, from single interactions in model wines to the investigation of the formation of complex macromolecules, brings the perfect story line to relate the relationship between phenolics and polysaccharides from the vineyard to the glass. Grape pectin is highly reactive toward grape and grape derived phenolics. Differences between grape cultivars or changes during grape ripeness will affect the extractability of these compounds into the wines. Therefore, the nature of the grape components will be crucial to understand the subsequent reactions occurring between phenolics and polysaccharide of the corresponding wines. It has been demonstrated that they can form very complex macromolecules which affect wine color, stability and sensory properties.

    Fine-scale environmental variation contributes to introgression in a three-species spruce hybrid complex2015In: Tree Genetics & Genomes, ISSN 1614-2942, E-ISSN 1614-2950, Vol. 11, no 1, article id 817Article in journal (Refereed)
    Abstract [en]

    Hybridization is common for many forest trees, where weak barriers to reproduction obscure species boundaries. We characterized the genomic structure of Picea populations comprising three species spanning two well-known contact zones, the Picea sitchensisxPicea glauca and the P. engelmanniixP. glauca hybrid zones, using a set of 71 candidate-gene single nucleotide polymorphisms. The genetic structure of populations suggests a complex genomic architecture shaped by interspecific gene flow and strong environmental selection, with increased genetic diversity in hybrids. The presence of admixture among all three species suggests that three-way hybrids with mixed ancestry occur where species ranges overlap in transitional environments. Significant clinal variation and associations with climatic variables (including continentality, temperature, and precipitation) differ between hybrid zones, indicating that individual species and their hybrids are adapted to distinct environmental niches. Allele-environmental association analysis revealed that most of the candidate genes with evidence of selection were unique to either the Sitkaxwhite or the Engelmannxwhite hybrid zones, with few shared between these zones. Management of these widespread and diverse gene pools will be best served through development of climate-based seed transfer, with recommended seed sources informed by a combination of genetic and climatic information for future climates.

    Enabling year-round cultivation in the Nordics: Agrivoltaics and adaptive Led lighting control of Daily Light Integral2021In: Agriculture, E-ISSN 2077-0472, Vol. 11, no 12, article id 1255Article in journal (Refereed)
    Abstract [en]

    High efficacy LED lamps combined with adaptive lighting control and greenhouse integrated photovoltaics (PV) could enable the concept of year-round cultivation. This concept can be especially useful for increasing the production in the Nordic countries of crops like herbaceous perennials, forest seedlings, and other potted plants not native of the region, which are grown more than one season in this harsh climate. Meteorological satellite data of this region was analyzed in a parametric study to evaluate the potential of these technologies. The generated maps showed monthly average temperatures fluctuating from −20 °C to 20 °C throughout the year. The natural photoperiod and light intensity also changed drastically, resulting in monthly average daily light integral (DLI) levels ranging from 45–50 mol·m−2·d−1 in summer and contrasting with 0–5 mol·m−2·d−1 during winter. To compensate, growth room cultivation that is independent of outdoor conditions could be used in winter. Depending on the efficacy of the lamps, the electricity required for sole-source lighting at an intensity of 300 µmol·m−2·s−1 for 16 h would be between 1.4 and 2.4 kWh·m−2·d−1. Greenhouses with supplementary lighting could help start the cultivation earlier in spring and extend it further into autumn. The energy required for lighting highly depends on several factors such as the natural light transmittance, the light threshold settings, and the lighting control protocol, resulting in electric demands between 0.6 and 2.4 kWh·m−2·d−1. Integrating PV on the roof or wall structures of the greenhouse could offset some of this electricity, with specific energy yields ranging from 400 to 1120 kWh·kW−1·yr−1 depending on the region and system design.
