摘要
通过对福建省罗卜岩自然保护区闽楠(Phoebebournei)种群的种子雨和种子库进行调查研究,结果表明,闽楠种群更新所依赖的种子库主要来源于母树最迟一年的种子雨输入;闽楠种群种子雨可分为E、S、M和L型;闽楠种群种子雨与径级大小密切相关;但结实的大小年现象存在有个体差异;闽楠种群种子雨高峰期出现于1月份,尤其是1月中旬;闽楠种群种子雨与气温、湿度、雨量及风速有关。
From the twenty first of December, 1995 to the tenth of January, 1996, seed rain of thirty six individuals of Nanmu population is calculated by means of 1 m 2 quadrats which are arranged under the average densed crowns of them. Meanwhile, forty eight quadrats whose volume are 0.05 m 3 (0.05 m× 1 m×1 m ) separately are chosen for the reaserch of seed bank of Nanmu population. The result finally includes: (1) seed bank of Nanmu population is stored by seed rain of individuals of Nanmu population which produces seeds at the latest year; (2) four types of seed rain, E. S. M and L are one by one discussed; (3) climaxes of seed rain curves appear mostly in January, 1996,especially during the middle period of this month; (4) amount of seed rain is closely related to the climate of this area, especially to humidity, and also to diameter size of individuals.
