  1. 1. Reproductive patterns of birches (Betula spp.) in northern Sweden

    Author : Stig-Olov Holm; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reproduction; Betula; seed-quality; seed-set; pollination; pollen-limitation; pollen-competition; tree-line; environmental gradient; seed weight; seedling survival; Semudobia;

    Abstract : The aim of this thesis was to study patterns of reproduction of Betula pendula and B. pubescens coll. along an altitudinal, coastal-inland, gradient in northern Sweden. The altitudinal variation was related to the distribution of the birch taxa along the gradient. READ MORE

  2. 2. Game of crops : genetic composition and adaptation of seed orchard crops

    Author : Alisa Heuchel; Xiao-Ru Wang; David Hall; Ulfstand Wennström; Jaroslaw Burczyk; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; seed orchards; GBS; linear deployment; tree improvement; genetic diversity; adapation; topgrafting; Scots pine; Norway spruce; improved reforestation material; field performance; flowering stimulation; fertility variation; Genetics; genetik; environmental science; miljövetenskap;

    Abstract : Orchard populations are artificial and intensively managed populations of elite, best-performing trees that are established for mass production of genetically improved seeds. Seed orchards connect cycles of selection, breeding, and testing of plus-trees with the deployment of the improved seeds at the operational plantations. READ MORE

  3. 3. Aggregation of gluten proteins - from wheat seed biology to hydrogels : scientific modelling based primarily on Monte-Carlo and HPLC methods

    Author : Joel Markgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gluten proteins are intrinsically disordered proteins that form extensive aggregated networks in wheat seeds, where they are stored as a nutrient source for the embryo. A modelling approach involving computational biology with Monte-Carlo algorithms and wet laboratory studies, including HPLC analysis, was applied to unravel the aggregational and hydrogelforming properties of the gluten proteins.

  4. 4. Pollination processes - maternal and offspring performance

    Author : Kristina Holmén Bränn; Kari Lehtilä; Pia Mutikainen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pollination; Sinapis arvensis; Brassica napus; Raphanus raphanistrum; Succisa pratensis; Evolution of flower size; Maternal plant responses; Resource allocation; Reproductive success; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Abstract : Pollination is one of the most important factors determining the reproductive success of plants. This thesis examines processes associated to varying pollination, with focus on plant responses. The first aim was to examine the possibility and constraints for short-term evolution of flower size in Raphanus raphanistrum. READ MORE

  5. 5. Potential of Canavalia gladiata as a food ingredient: Nutritional and Functional aspects

    Author : Sagarika Ekanayake; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Canavalia gladiata; Sword beans; Nutritional quality; Functional properties; Näringslära; Nutrition;

    Abstract : The tender fruits of the leguminous plant Canavalia gladiata (Sinhala awara, sword beans) are consumed in Sri Lanka as a green vegetable. The mature seeds are also utilized in a variety of ways but not very frequently, in spite of desirable agronomical properties, for cultivation in the country. READ MORE
