芒作为野生稻中普遍存在的一个结构，可以帮助种子散布，同时防止鸟兽啄食。

As the common structure in the wild rice species , awn can help seed dispersal , and prevent birds or animals from eating .

随着北美车前种群定居时间延长，种群密度的增加，其斑块数目呈现出少→多→少的变化趋势，这一特点与其种子散布机制有关；

The number of the population patches followed an order as less → more → less , which was related to their seed spread characteristics ;

有效的种子散布是木本植物形成入侵种需要经历的过程之一，但在预测入侵种时却常常被忽略。

Effective dispersal is one essential course for invasive species on their process of invasion , while study on the effectiveness of seed dispersal was often neglected when predicting species invasion .

经测算，锥连栎种子散布后的主要命运是动物捕食和转移，种子的保存率和萌发率分别仅占到单个树木种子产量的059%和195%。

By measuring , the main fortune of seeds after dispersal was animal predation and transfer , and the retaining and germinating seeds respectively occupied 0.59 % and 1.95 % of the single seed production .

干旱区的植物，除了具有独特的结构或方式适应干旱环境外，在种子散布和种子萌发方面，也各自具有独特的机制与干旱环境相适应。

The plant which grows in arid area has peculiar structure or way to adapt to the dry environment . In seed dispersal and seed germination , it also has peculiar mechanism adapting to the dry environment .

种子的散布主要受湿度和风的影响，湿度对种子雨的强度起主要作用。

Humidity and wind had great effects on the seed dispersal .
