以砂生槐种子为材料,利用清水、300 mg·L-1和600 mg·L-1GA3浸泡种子2 d、4 d和8 d,探讨不同处理对砂生槐种子萌发特性的影响.结果表明,随着浸泡时间的延长,砂生槐种子的发芽率有所提高,而且4~8 d的300 mg·L-1 GA3浸种可显著提高砂生槐种子的发芽率,相比清水浸泡发芽率提高10%~15%.对于发芽势,清水、300 mg·L-1及600 mg ·L-1 3种处理在浸泡2d和8d后只有一个发芽势高峰,而浸泡4 d后有两个发芽势高峰.同时,方差分析结果表明,发芽率在9种不同处理间呈极显著差异,腐烂率呈显著差异,但硬实率在不同处理间没有显著差异.
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.
