  1. 1. Odlingsavståndets betydelse för korspollinering i böna (Phaseolus vulgaris) : en nordisk fältstudie baserad på hypokotylfärg som morfologisk markör

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

    Författare :Anne Schultz; [2023]
    Nyckelord :Korsbefruktning; inkorsning; genetisk mångfald; genbank; NordGen; fröuppförökning;

    Sammanfattning : Syftet med denna uppsats är att undersöka hur odlingsavståndet mellan olika accessioner av böna, Phaseolus vulgaris påverkar sannolikheten för inkorsningar. Phaseolus vulgaris klassas som en i huvudsak självpollinerande gröda men studier har visat att inkorsningar i P. 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. Tritrophic interactions with Silphium integrifolium at the axis : elucidating the role of arbuscular mycorrhizal fungal species on plant phenotype

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Philipp Hansen; [2023]
    Nyckelord :Arbuscular mycorrhiza; mycorrhizal responsiveness; induced plant volatiles; Silphium integrifolium Silflower ; perennial grains; new crops; ecological intensification;

    Sammanfattning : A fundamental understanding of the intricate interactions between crops and their environment may help guide the development of ecologically intensified agriculture. Arbuscular mycorrhizal fungi (AMF) are root symbionts that can increase a plant’s access to soil resources and have been found to reprogram plant defensive mechanisms, potentially influencing the performance of plant antagonists.

  5. 4. Identifying molecular markers for breeding a future oil crop, Lepidium campestre

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

    Författare :Noomi Lodenius; [2023]
    Nyckelord :glucosinolate content; interspecific hybridization; Lepidium campestre; marker discovery; oil content; oil quality;

    Sammanfattning : The cold hardy novel oil- and cover crop Lepidium campestre is currently being domesticated as a potential oil crop for the Nordic region. To achieve this objective, multiple traits have previously been identified as desirable to improve, including seed oil content and composition, and glucosinolate (GL) content. LÄS MER

  7. 5. Safeguarding a Safeguard: Assessing the Status of Global Ex-Situ Crop Conservation and the Svalbard Global Seed Vault’s Role in its Protection

    Magister-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Christopher Keegan; [2022]
    Nyckelord :Svalbard Global Seed Vault; Genebanks; Genetic Resources; Genetic Erosion; Passport Data Completeness; Agriculture and Food Sciences;

    Sammanfattning : The Svalbard Seed Vault serves as a backup against accidental loss of genetic crop diversity within the existing global conservation system. Addressing this objective, this thesis repeats the 2013 assessment of the Seed Vault’s completeness relative to the global conservation system as performed by Westengen et al (2013, 1). LÄS MER
