Abstract

The aim of this research is to classification of soil seed bank in Populus Caspica Protected Area. The study of above ground vegetation and soil seed bank were carried out with Braun-Blanquet and seedling emergence method respectively. Results showed that size of soil seed bank in upper layer (713 seeds per m2) were significantly lower than depth layer (1163 per m2) but species richness from 42 to 28 species were reduced with increasing the soil depth. The result also showed that based on the whole plants from the region (65 species) only 35 species were classified in the persistent soil seed bank. Generally, we are concluded main, late-successional, species have not the ability to producing persistent soil seed bank, so the restoration of extant vegetation cannot rely on the soil seed bank in case of the overall habitat is destroyed.
