  2. 1. 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

  4. 2. Get in tune : chloroplast and nucleus harmony

    Author : Dmitry Kremnev; Åsa Strand; Francis-Andre Wollman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; development; gene expression;

    Abstract : Photosynthetic eukaryots emerged as a result of several billion years of evolution between proeukaryotic cell and ancestral cyanobacteria that formed modern chloroplasts. The symbiotic relationship led to significant rearrangements in the genomes of the plastid and the nucleus: as many as 90 % of all the plastid genes were transferred to the nucleus. READ MORE

  5. 3. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness

    Author : Johanna Eneström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; weediness; Clonal plant; resource sharing; resource storage; partitioning of genetic variation; seedling development; seed recruitment; Aegopodium podagraria;

    Abstract : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

  6. 4. Stand development effects on N₂-fixation and seedling performance in northern boreal forests

    Author : Babs Stuiver; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : For large parts of the Swedish boreal forests, stand development starts with clear-cutting. Still, much is unknown about how stand development affects ecosystem processes and how these processes are driven by changes in vegetation and soil properties that occur during stand development.
