  1. 1. Spring water stress in Scots pine: interaction of snow and soil temperature

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

    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.
