    Abstract : Norway spruce (Picea abies L. Karst) is a conifer belonging to the group gymnosperms and is an ecologically and economically important species in several parts of Europe. READ MORE

  4. 2. From growth cessation to bud burst : conifer seedling development in response to nursery culture and environmental stimuli

    Author : Elisabeth Wallin; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; Pseudotsuga menziesii; seedling status; gene activity; photoperiod; storability; vitality; transplants; shoot electrolyte leakage; Picea abies; Pinus sylvestris; Pseudotsuga menziesii; plantstatus; genaktivitet; fotoperiod; lagringsbarhet; vitalitet; omskolningsplantor; elektrolytiskt läckage; Energy and Built Environments; Energi och samhällsbyggnad;

    Abstract : In Sweden, 350-400 million seedlings are produced annually for forest regeneration. About one third of these are overwintered in frozen storage, necessitating accurate methods to assess storability. Young transplants of Norway spruce (Picea abies (L.) Karst. READ MORE

  5. 3. Molecular Regulation of Bud Phenology and Vegetative Phase Change in Populus Trees

    Author : Shashank Sane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Trees are sessile organisms that have evolved to survive and thrive in changing growth conditions. As a survival strategy they undergo massive morphological changes that can be quantified. READ MORE

  6. 4. Understanding the environmental regulation of tree phenology

    Author : Tetiana Svystun; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phenological events; environmental cues; temperature response; phenological modelling; frost risk; gross primary production; climate change impact;

    Abstract : In temperate and boreal climates, trees synchronise their annual growth cycles with seasonal changes in daylength and temperature. Understanding how environmental cues regulate tree phenology is important to our ability to capture the potential responses of trees to climate change, with implications for forest productivity.

  7. 5. Adaptive Evolution and Demographic History of Norway Spruce (Picea Abies)

    Author : Thomas Källman; Peter Tiffin; Uppsala universitet; []
    Keywords : ;

    Abstract : One of the major challenges in evolutionary biology is to determine the genetic basis of adaptive variation. In Norway spruce (Picea abies) the timing of bud set shows a very strong latitudinal cline despite a very low genetic differentiation between populations. READ MORE
