    Detta är en avhandling från Uppsala : SLU, Dept. of Environmental Assessment

    Författare :Per-Erik Mellander; Mittuniversitetet.; Mittuniversitetet.; Sveriges lantbruksuniversitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Low temperature; soil warming; transpiration; root water uptake; carbon dioxide assimilation; soil frost; silvicultural practice; Pinus Sylvestris;

    Sammanfattning : Water use and net carbon assimilation during spring was examined on Scots pine trees exposed to different soil warming dynamics in the field. Sap flow, needle water potential and net carbon assimilation were measured on trees that were exposed to a wide range of soil temperature regimes caused by manipulating the snow cover on tree-scale soil plots.

  3. 3. Pine weevil feeding in Scots pine and Norway spruce regenerations

    Detta är en avhandling från Uppsala : SLU, Dept. of Environmental Assessment

    Författare :Kristina Wallertz; Sveriges lantbruksuniversitet.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Damage caused by the pine weevil, Hylobius abietis (L) feeding on conifer seedlings is a major problem in reforested areas in many parts of Europe. The adult weevil feeds on the stem-bark of young seedlings, frequently killing a large proportion of newly planted seedlings. LÄS MER

  4. 4. Foliar fungi of Scots pine (Pinus sylvestris)

    Detta är en avhandling från Uppsala : SLU, Dept. of Environmental Assessment

    Författare :Hanna Millberg; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Scots pine (Pinus sylvestris) is an ecologically and economically important tree species in Fennoscandia. Scots pine needles host a variety of fungi, some with the potential to profoundly influence their host. These fungi can have beneficial or detrimental effects with important implications for both forest health and primary production. LÄS MER
