 abstract={The size, species composition and spatial structure of the seed bank in the soil were studied in four uneven-aged old fields, in early Peucedano-Pinetum forest succession phases. In the seed bank of the successional ecosystem series the following phenomena have been found: (1) decrease in the number of seed and species, (2) increased seasonal stability of the numbers and species composition of seeds, (3) presence of all the species occurring in the phytocoenosis, and a similar list of dominants, (4) similar type of seed distribution in the soil. A significant influence has also been found of the vegetation structure on the seed rain to seed bank ratio, as well as a low germination percentage of seeds accumulated in the surface soil layer.},
