  5. 14. New insights into growth cessation and dormancy in trees

    Författare :Lars Resman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Since trees are sessile they have evolved elaborate mechanisms that anticipate oncoming winter and allow the trees to withstand extreme changes in their environment. Trees need to stop growth and initiate cold hardiness well before cold temperatures become damaging, consequently the timings of growth cessation and dormancy are important adaptive traits for their ability to survive in harsh winter conditions.

  7. 15. Molecular analysis of growth cessation and dormancy in hybrid aspen

    Författare :Szymon Tylewicz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Perennial plants such as trees living in temperate zones experience extreme changes in temperature during summers and winters. In order to survive, shoot apical and cambial meristem undergo a transition from active growth to dormant state, well in advance of winter onset. LÄS MER
