Effects of lichen, Sphagnum spp. and feather moss leachates on jack pine and black spruce seedling growth

The main objective of this study was to evaluate the influence of leachates from three typical boreal forest ground layers on young tree growth and to explore the linkages between the chemical composition of the leachates, tree growth, the allocation between belowground and aboveground parts, and ectomycorrhizal colonization. An original 6-month greenhouse experiment was set up to investigate (i) the effects of lichen (Cladonia spp.) and feather...
