  4. 3. Secrets of the Seeds : exploring the relationship between seed morphology and seed quality in Lepidium campestre, a novel oil crop for Northern Sweden

    Kandidat-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Ludvig Pettersson Landgren; [2023]
    Nyckelord :Lepidium campestre; field cress; oil crop; plant breeding; domestication; seed morphology; seed colour; seed analysis; Northern Sweden; glucosinolate;

    Sammanfattning : This study set out to explore relationships between seed morphology and qualitative traits in field cress, Lepidium campestre, with the goal of assisting the breeding process of this crop under domestication. A collection of seeds of L. campestre as well as related species was analysed for weight and size using a MARViN seed analyser. LÄS MER

  5. 4. The effect of life history and weather on onset of flowering and length of flowering period of agricultural weeds

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Amanda Karpaty Wickbom; [2023]
    Nyckelord :global warming; agricultural weeds; first flowering; flowering phenology;

    Sammanfattning : With a warming climate and the usage of monocultures in food production it is possible we may face more issues concerning food insecurity in the future as pollinators struggle to find food in agricultural landscapes. Therefore, it is of value to know whether common agricultural weeds are important sources of food for pollinators. LÄS MER

  7. 5. Pollinator communities on a landscape complexity gradient in southern Sweden

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Hanna Olsson; [2023]
    Nyckelord :pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

    Sammanfattning : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. LÄS MER
