摘要
植物种群不但在生长阶段具动态特性,在种子阶段也是如此(Moore,1986),而种子萌发是联结这两个阶段,使植物完成生活史的重要环节。
This was a review about the advance of seed germination in its natural environment in the last fiften years. the ecological effect of environmental facters on seed germination in the field, such as water, tempera ure, light, oxygen, chemical compound were discussed. Among these factors, the combination of water and temperature fluctuation is most important to seed germination. The genitics characteristics of seed determine germination behaviour. Seeds tend to reach more germination at gaps or safesites, which can arise from disturbance of nature and human or animal activities.
