Abstract
A preliminary investigation on the diaspore and soil seedbank was conducted with soil samples collected from Modhupur Sal (Shorea robusta Gaertn.) forest of Bangladesh. A total 47 types of both monocotyledonous (21) and dicotyledonous (26) seedlings of different plant species were found t o germinate in this experiment. The highest number of seedling population in monocotyledonous and dicotyledonous plants belonged to Axonopus compressus (Swartz.) P. Beauv. (total number-506) and Bacopa monnieri (L.) Penn. (total number-131) respectively. All the seedlings emerged from soil seed-bank belonged to five monocotyledonous and twelve dicotyledonous plant families where, representatives from Gramineae and Compositae were the maximum. Lifeform spectra showed the highest proportion of hemicryptophytes among the germinated plants and in respect to habit, most of the plants (about 85%) were herbaceous.
