摘要：

以花木蓝种子为试验材料,采用不同处理方式研究了其硬实性及萌发特性。结果表明,种子千粒质量为15.744 g,未经处理的种子吸水率为28.49%,明显低于经浓H2SO4处理9 min种子的吸水率。种子硬实率为56%,硬实种子采用浓H2SO4处理,以9 min为宜,发芽率为70.67%,发芽势为68%;不同温度水处理中,50℃水恒温处理效果最理想,发芽率和发芽势分别85.33%、84%;机械损伤能够提高花木蓝种子萌发率,但是污染率较高,萌发效果不理想。最适萌发温度为20～25℃。

摘要：

The seed germination characteristics of Indigofera kirilowii were studied with different treatments in this paper. The results showed that the weight per thousand granule was 15. 744 g. The water absorption rate of untreated seeds was 28. 49%,significantly lower than that of treated by H 2 SO 4 for 3 min. The hard seed rate reaches to 56%; the hard seeds of I. kirilowii could be broken down by H 2 SO 4,the most appropriate time was 9 min,the germination rate was 70. 67% and germination vigor was 68%; The germination rate pre-treated by hot water( 50 ℃) was 85. 33% and germination vigor was 84%; the germination rate by mechanical wounding could be improved. The optimum germination temperature of the seeds was 20- 25 ℃.
