  1. 6. Characterization of adventitious root formation in Populus species and Norway spruce

    Författare :Sanaria Alallaq; Catherine Bellini; Carmen Diaz-Sala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious root; Conifers; Picea abies; auxin; cytokinins; jasmonate; red light; Populus spp.; hybrid poplar; hybrid aspen; cambium; stem cuttings; P. tremula; Swedish Aspen SwAsp collection;

    Sammanfattning : Adventitious root (AR) formation is a form of post-embryonic development and is a key adaptive trait in plants. De novo adventitious root regeneration represents an elegant evolutionary innovation that allows many plant species to multiply through vegetative propagation; it is widely used in forestry and horticulture to multiply elite genotypes.

  2. 7. Ethylene and Auxin in the Control of Wood Formation

    Författare :Jenny Maria Hellgren; SLU; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; auxin ; ethylene ; lignification ; growth rate ; fibres ; cambium ; gas chromatography ; reaction wood ; organic acids ; mass spectrometry ; populus tremula ; pinus sylvestris; biology; biologi;

    Sammanfattning : This thesis considers aspects of the regulation of growth rate and fibre properties in forest trees. These properties are both genetically determined and influenced by environmental stimuli. Induction of reaction wood is an environmentally induced process involving changes in growth rate and fibre properties that can be readily studied. LÄS MER

  3. 8. Distribution and regulation of auxin in Arabidopsis root cells

    Författare :Sara Petersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The plant hormone auxin (IAA) coordinates many of the important processes in plant development. For example, IAA is critical for normal embryogenesis, root development, cell elongation, and the tropic responses such as gravitropism and phototropism. LÄS MER

  4. 9. The role of auxin in abscission of organs and tissues

    Författare :Xu Jin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Most deciduous trees drop their leaves before winter, a process which is referred to as leaf abscission. Leaf abscission is thought to be regulated by the action of auxin and ethylene. LÄS MER
