1. Effects of shade and humus fertility on boreal forest tree seedling growth, competition and mycorrhizal colonisation
L3-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : In boreal forest ecosystems, growth of tree seedlings is limited by resources both aboveground (through shading) and belowground (through nutrient limitation), and the ability to tolerate or avoid these conditions is important in determining the relative performance of different tree species. Two of the means to compete for these resources, are through increasing stem-elongation to escape shading by neighbours (shade avoidance), and through mycorrhizal symbiosis that may increase the nutrient- and water up-take.
