Abstract

Little information is available concerning the seed content of tropical soils. The present study was designed to determine the nature of the seed load in forest soil from virgin mixed dipterocarp forest adjacent well-established belukar and an area of belukar that had been newly cleared and burnt for shifting cultivation. The results showed that soil of virgin forest nearby well-established1761 belukar and newly cleared and burnt belukar were all carrying a load of viable seed. However the seed load of the virgin forest was very small not very variable in size from site to site and consisted primarily of belukar species even though such species were not to be found among the standing vegetation of this forest except at its margin. The seed probably arrives by animal or bird dispersal rather than by wind dispersal and is probably inhibited from germination by the low light intensity within the forest. The seed load of soil of the belukar areas is much larger and more variable in size from site to site. This is probably due to localization of seed-producing plants and relatively local wind dispersal of seed of many of these pioneer belukar species. This seedload comprised entirely of belukar spec
