Variability of the soil seed banks in the natural deciduous forest in the Bialowieza National Park

摘要

Using the germination method, the species diversity, density of the soil seed band and its relation to cover vegetation in a natural deciduous forest with primary and secondary tree stand were compared. It was found that the mean density and species composition of the soil seed bank in the forest with secondary tree stand that has spontaneously been overgrown over the last 90 years after clear-cutting does not differ from the soil seed band derived from primeval forest(3157m~-2vs. 3827m~-2). In both stands there were 46 species altogether and 36 were common and seed banks were dominated by herbs.
