  1. 1. Phyllosphere of organically grown strawberries

    Författare :Justine Sylla; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The use of biological control agents (BCAs) is regarded as a promising measure to control important foliar strawberry diseases such as grey mould (Botrytis cinerea) and powdery mildew (Podosphaera aphanis) in the organic strawberry cultivation. However, the use of biological control agents (BCAs) in the phyllosphere is still challenging as this environment is very harsh and dynamic, in particular under field conditions. LÄS MER

  2. 2. Interception and storage of wet deposited radionuclides in crops

    Författare :Stefan Bengtsson; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The emission of radionuclides into the atmosphere from various sources, such as nuclear power plant accidents and nuclear bomb explosions, can result in the interception and uptake of radionuclides by crops in the agricultural ecosystem. These radionuclides e.g. LÄS MER

  3. 3. Studies of plant interactions with other organisms to understand Bacillus mediated stress management

    Författare :Anna Johansson; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The naturally evolved plant defense system is not always effective, due to adaptations among the attackers. Crop protective chemicals have many negative effects on the environment. Ecosystem services, like beneficial microorganisms, are of great interest for plant stress management in sustainable crop production. LÄS MER

  4. 4. Size matters

    Författare :Anna Åsman; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. LÄS MER

  5. 5. Industrial Symbiosis in the Biofuel Industry Quantification of the Environmental Performance and Identification of Synergies

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Michael Martin; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial symbiosis; life cycle assessment; by-product; integration; environmental performance;

    Sammanfattning : The production of biofuels has increased in recent years, to reduce the dependence on fossil fuels and mitigate climate change. However, current production practices are heavily criticized on their environmental sustainability. LÄS MER
