We hypothesised that the decomposition rates of leaf litter will increase along a gradient decreasing fraction European beech (Fagus sylvatica) and increasing tree species diversity in generally beech-dominated Central temperate deciduous forests due to an quality. studied including its lignin monospecific (pure beech) stands with up five genera (Acer spp., Carpinus betulus, Fagus sylvatica, Fraxinus excelsior, Tilia spp.) using litterbag approach. Litter was more rapid stand-representative from multispecific than pure stands. Except for litter, species-specific did not differ significantly among stand types, but were most excelsior slowest interspecific comparison. Pairwise comparisons other (except Acer platanoides) revealed "home field advantage" 20% (more high own different composition). Decomposition mixtures displayed additive characteristics, predicted by individual species. Leaf positively correlated initial N Ca concentrations negatively C:N, C:P lignin:N ratios. The results support our hypothesis overall are mainly influenced chemical composition Thus, seems be important itself.
