  1. 1. Recirkulering av restprodukter och gynnande av arbuskulär mykorrhiza : två möjliga faktorer i strävan mot ett hållbart fosfornyttjande?

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Karl-Johan Fabo; [2018]
    Keywords : mykorrhiza; arbuskulär mykorrhiza; fosfor; fosforbrist; växtnäring; kretsloppsprodukter; restprodukter; tungmetaller; organiska föroreningar;

    Abstract : Låg förekomst av växttillgänglig fosfor är en begränsande faktor för grödors tillväxt på många odlingsmarker. Under det senaste århundrandet har odlare i allt högre utsträckning kommit att använda mineralgödsel för att kunna erhålla tillräckligt stora skördar. READ MORE

  2. 2. Characterisation of the epistatic hybrid incompatibility locus STRUBBELIG RECEPTOR FAMILY 3 in Arabidopsis

    University essay from SLU/Department of Plant Biology (from 140101)

    Author : Fredrik Dölfors; [2018]
    Keywords : abiotic stress; arabidopsis; co-evolution; hybrid incompatibility; receptor-like kinase;

    Abstract : Populations of Arabidopsis thaliana have spread throughout temperate zones of the world and adapted to prevailing biotic and abiotic stress factors. Diverging popula-tions of Arabidopsis accessions can evolve postzygotic hybrid incompatibility (HI). READ MORE

  3. 3. Biodiversity in assisted migration trials : a study comparing the arthropod diversity between different populations of cottonwood (Populus Fremontii) translocated to new areas

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Maria Noro Larsson; [2018]
    Keywords : assisted migration; biodiversity conservation; arthropods; climate change;

    Abstract : This study aims at investigating how diversity and community structure of arthropods are affected by assisted migration of foundation species. This is proposed to counter biodiversity loss in the tracks of climate change. By focusing on foundation species, a larger quantity of biodiversity could be protected. READ MORE

  4. 4. Effects of cover crops and limiting resources on biomass allocation in Elymus repens (L.) Gould

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Ines Prieto; [2017]
    Keywords : elymus repens L. gould; couch grass; cover crops; competition; light; nutrients; weeds in organic farming; perennial weed;

    Abstract : Weed control has always been a major challenge in arable lands. Elymus repens (couch grass), a rhizomatous perennial grass, is a particularly problematic weed in both annual and perennial crops in temperate climates. E. repens is dominant particularly in farming systems with no or limited use of herbicides. READ MORE

  5. 5. Deciphering mechanisms of Bacillus amyloliquefaciens mediated priming of plant growth and defense responses

    University essay from SLU/Department of Plant Biology (from 140101)

    Author : Anna Törnkvist; [2017]
    Keywords : Arabidopsis thaliana; Bacillus amyloliquefaciens UCMB5113; biocontrol; brassinosteroids; induced systemic resistance; priming;

    Abstract : Beneficial bacteria colonizing plant roots are capable of mediating improved plant growth and enhanced defense responses against biotic and abiotic stresses. Such colonization has been suggested to accumulate brassinosteroid (BR) levels but the mechanisms behind this is not yet completely understood. READ MORE
