Species diversity and density of buried seed bank in top 10cm. (0-5 cm and 5-10cm) of soil were studied in two tropical dry deciduous forests in Central India. Two sites namely, Mainpani and Ramna were selected for present study. Samples were collected 0-5 cm and 5-10 cm in three seasons, viz. postmonsoon, winter and summer. Seeds of total 34 species were recovered from soil samples belonging to 17 species of trees, 4 of shrubs and 13 of herbs. Result showed that highest density in upper layer (0-5 cm) was that of Anogeissus pendula (800 m-2 ) under inter canopy area in winter season at Mainpani. Maximum densities in case of shrub and herb species was found to have been contributed by Lantana camara (175 m-2 ) under canopy and Cassia tora (850 m-2 ) under inter canopy during summer and winter sampling at Ramna.Keywords

The present paper deals with the composition of soil seed banks and vegetation in selected tropical dry deciduous forests sites. The primary objective is to provide data of this kind so as to establish the relationship between the soil seed bank composition with extent vegetation. Important factors which influence the composition of soil seed banks in forest include the dispersal mechanism of seeds, losses due to anthropogenic activities, damage due to fire, diseases, physiological death, decomposition and predation by animals. Result of the present study indicate the poor species richness in soil seed banks structure and composition as compared to above ground vegetation at the study site.Keywords
