    Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER

  3. 17. Rhizobacteria associated to Vitis vinifera and their effect on the control of Xiphinema index, Meloidogyne ethiopica and Vitis growth

    Författare :Erwin Aballay; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. LÄS MER

  4. 18. Understanding the Molecular Basis of Differential Growth during Apical Hook Development

    Författare :Kristoffer Jonsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plants’ adaptation to their environment often involves change in development, which in many cases involves the establishment of differential growth rates across organs, for instance during phototropic and gravitropic responses. A striking example of differential growth is the formation of the apical hook, a structure that forms to protect the apical meristem as seedlings penetrate through soil. LÄS MER

  5. 19. Genome-wide analyses of Bacillus amyloliquefaciens strains provide insights into their beneficial role on plants

    Författare :Adnan Niazi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The innate immunity system of plants provides a basal defence barrier to most microorganisms. However, many plant pathogens have evolved to overcome this defence. Certain bacteria in the PGPB (plant growth promoting bacteria) category that improve plant growth have also been found to improve plant defence against insect pests and pathogens. LÄS MER

  7. 20. The role and use of water in agriculture in the Western Balkans: the case of Macedonia

    Författare :Jordan Hristov; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : This thesis examines the role and demand for water in Macedonia from an economic perspective with an emphasis on agricultural use. The first paper provides an overview of the Macedonian agricultural sector and assesses the productivity growth in the period 1999-2010. In the study period, the sector experienced an average increase in volume of 1. LÄS MER
