  1. 1. 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

  3. 2. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clàudia Fernández Mestre; [2023]
    Nyckelord :Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Sammanfattning : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. LÄS MER

  4. 3. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Johan Per Michael Svedin; [2022]
    Nyckelord :Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

    Sammanfattning : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.

  7. 5. Flowering phenology, pollination and seeding interactions in Garden Lupine (Lupinus polyphyllus)

    Kandidat-uppsats, Karlstads universitet

    Författare :Amanda Boström; [2020]
    Nyckelord :pollination; Garden Lupine; bumblebee; Bombus; Lupinus polyphyllus; self-pollination; pollinering; blomsterlupin; humlor; Bombus; Lupinus polyphyllus; självpollinering;

    Sammanfattning : The spreading of the invasive plant Garden Lupine (Lupinus polyphyllus) has become a matter of national importance in Sweden, due to it posing a threat to native plant and pollinator diversity. The effective attraction of bumblebees (Bombus spp. LÄS MER
