野生大豆种子雨的研究

Seed rain of Glycine soja

对野生大豆种子雨的时空动态及其与外界天气情况关系的初步研究表明，在野 生大豆整个种子雨的历程中，出现３个较为明显的炸荚和种子散落的高峰，并且峰的出现 与天气晴朗（相对湿度）相关，而与气温相关性不大．野生大豆种子雨的空间分布格局主要 是野生大豆种子炸荚的自身习性（炸荚弹力）和荚本身在植株上的空间分布有关，而与风 向（风力≤７级）关系不大．

Studies on the temporal and spatial dynamics of Glycine soja seed rain and its relationship with meteorological factors show that there are three peaks in the course of pod exploding and seed dispersing, which are related to fine day (relative humidity), but little to temperature. The temporal distribution pattern of seed dispersal is depended on the exploding habit(exploding force) of pod and its location on the plant, but has no relation to wind direction(wind force rank 7 on the Beaufort scale).
