Preliminary Study on the Seed Rain and Seed Bank of the MixedEvergreen and Deciduous Broad-Leaved Forest on Fanjing Mountain

The seed rain of the mixed evergeen and deciduous broad-leaved forest on Fanjing Mountain,i.e. Fagus lucida. Illicium ternstroemioides community, is 260 m-2 of 18 species. The amount of theripe germinative seeds in the seed rain is 80 m- 2. At the beginning of the natural germination of the seedbank, the viable seeds in the seed bank are 2 076 m-2 of 33 species. Of the viable seeds, the presentplant seeds are 204 m-2 of 18 species, the seral earlier species seeds are 1 872 m-2 of 15 species. Theviable seeds belong to 20 woody species and 13 heth species. All the seeds in the litter of the seed bankare produced by the present plant. The species and the amount of the viable seed in the soil reduce grad-ually with the depth increasing of the soil. At the beginning of the natural germination of the seed bank,there are many viable seeds of the present plants in the seed bank. The regenerative potential of the pre-sent commnity is good.
