为了研究银叶金合欢种子的播种前处理方法,促进其种子萌发,采用不同温度的热水和浸种时间以及不同体积分数的浓硫酸和浸种时间对银叶金合欢种子进行浸种处理。结果显示,100℃热水处理24 h和98%硫酸处理20 min对于破坏银叶金合欢种子种皮、提高其发芽率均有很好的促进作用,2种处理方式的种子发芽率分别为83.33%和86.67%。其中热水处理硬实种子较多,而硫酸处理的种子腐烂率相对较高。

In order to promote the seed germination of Acacia podalyriifolia, the A. podalyriifolia seeds were treated by hot water with different temperature and time, and by sulfuric acid with different concentration and time,so as to select the good pretreatment method. The results showed that they were good for destroying A. podalyriifolia seed coat and improving the germination rate by 100 ℃ hot water treating for 24 h and 98% sulfuric acid treating for 20 min,the seed germination rate were 83. 33% and 86. 67% respectively. The number of hard seed was more in treatment of hot water,and the decay rate was relatively higher in treatment of sulfuric acid.
