The study shows that the early and late seed rains of constructive tree species in evergreen broadleaved forest at chongqing simian mountain had no activity. the bigger the seeds of the species and the earlier or later the seeds of the species matured, the higher the proportion of the seed rain damaged by animals. the quantitative variation of seed rain, active seed rain and seed bank did not take place at the same time. at early time, the number of seed banks of castanopsis fargesii, lithocarpus glabra, quercus myrsinrefolia, castanopsis plasyacantha, cinamomum subavenium. which own more active seed rain increased by geomitric series. the seed banks of castanopsis orthacantha and schima argentea were small, only survived a short time, and did not sprout next year. the quantitative dynamics of seed banks and their increasing or decreasing rates were decided by the proportion damaged by animals, dying speed of seeds and their resistance to pathogens and adverse circumstances, and the state of seed germination
對重慶四面山常綠闊葉林建群種種子雨、種子
庫的研究表明,建群種早期和晚期的種子雨無活力;種子偏早或偏晚成熟及大籽粒的樹種,其種子雨被取食的比例大;種子雨、有活力種子雨、種子
庫三者的數量變化不一致;有活力種子雨量較大的栲、石櫟、小葉青岡、扁刺栲、香桂等,其種子
庫密度在早期以近幾何級數的方式增長,元江栲、銀木荷種子
庫小,存在時間短,翌年無一年生萌發苗;種子
庫數量動態、消減率動態決定於種子被取食的強度、種子衰老的速度以及種子對病菌、逆境的抗性和種子萌發的整
