    Sammanfattning : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. LÄS MER

  5. 4. Nitrogen uptake and assimilation during Norway spruce somatic embryogenesis : investigating the role of glutamine

    Författare :Johanna Carlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Sweden is currently experiencing shortage of Norway spruce (Picea abies) seeds due to e.g. irregular flowering and the recent year’s outbreaks of pests and pathogens destroying cones and seeds. LÄS MER

  7. 5. Enhancing spruce defence against an insect pest : effects of somatic embryogenesis and methyl jasmonate treatment

    Författare :Kristina Berggren Nieto; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Enhancing plant resistance against pests has the potential to become a sustainable alternative within forestry. Exogenous application of the plant defence signalling hormone methyl jasmonate (MeJA) as well as propagation through somatic embryogenesis (SE) has been shown to increase Norway spruce (Picea abies) plant’s resistance to the major forest regeneration pest the pine weevil Hylobius abietis.
