    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nutrient-efficient and high-yielding spring wheat is needed in high-latitude regions. The aims of this thesis were: (1) to evaluate the effects of soil compaction and differential weather conditions on plant growth and grain yield, (2) to identify critical nutrient elements limiting plant growth and grain yield, and (3) to identify root and shoot traits at an early growth stage (early vigor) influencing nutrient use efficiency and grain yield of spring wheat.

  4. 3. Pollination processes - maternal and offspring performance

    Författare :Kristina Holmén Bränn; Kari Lehtilä; Pia Mutikainen; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. The Affective Profile Model: ill-being and well-being

    Författare :Erica Schütz; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; affective profile; affect; ill-being; well-being; character;

    Sammanfattning : Positive and negative affect have emerged as significant independent dimensions in studies of affective structure. Seeing affect as composed of two systems that can be categorized in high and low enables the possibility of four different combinations (i.e. LÄS MER
