Effects of Soaking Time and GA3 on Seed Germination of Sophora moorcroftiana
The study is to explore the effects of different treatments on the germination characteristics of Sophora moorcroftiana seeds,in which the seeds were soaked in water,300 mg·L-1 and 600 mg·L-1 GA3 for 2,4,and 8 days.The results showed that with the extension of soaking time,the germination rate of S.moorcroftiana seeds increased,and soa-king with 300 mg·L-1 GA3for 4-8 days can significantly improve the germination rate,which is 10%-15%higher than soaking with water.For germination-vigor,there was only one peak of germination-vigor after soaking for 2 days and 8 days in water,and GA3 300 mg·L-1 and 600 mg·L-1 treatments,while there were two peaks after soaking for 4 days.Meanwhile,the analysis of variance results showed that there were extremely significant differences in germination rate and decay rate among 9 different treatments,but there was no significant difference in hard seed rate among different treatments.
