  3. 2. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE

  4. 3. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Fayez Altabbaa; [2022]
    Keywords : Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Abstract : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. READ MORE

  5. 4. Genetic and Experimental investigations of the pathogenicity of Sindbis virus genotypes.

  6. 5. Arbuscular mycorrhiza in landrace and modern wheat : its impact on plant performance and how it is influenced by plant breeding and modern cropping practices

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Klara Yngve; [2020]
    Keywords : arbuscular mycorrhiza; landrace varieties; modern cultivars; wheat; conventional cropping systems; organic cropping systems;

    Abstract : Modern agriculture has a negative impact on climate and environment and is challenged by climate change. A transition to a more sustainable, secure and yet high food production is necessary. Landrace cereals attract attention for their ability to sustain nutrient deficiency, drought and harsh climate conditions. READ MORE
