| 摘 要： | 目的]探讨植物激素对坚龙胆种子萌发的影响。方法]以坚龙胆成熟种子为试验材料,采用正交试验设计研究赤霉素(GA3)、6-苄基腺嘌吟(6-BA)、吲哚乙酸(IAA)及浸种时间对坚龙胆种子发芽情况的影响。结果]坚龙胆种子发芽过程中以200 mg/L GA3+5mg/L 6-BA+5 mg/L IAA配比并浸种48 h处理的效果最好,种子发芽率达93%以上,种子开始发芽时间和发芽持续时间短,发芽势和发芽指数最高。结论]经过正交试验设计优选出影响坚龙胆种子发芽率的作用大小为IAAGA3浸种时间6-BA;经过植物激素处理可以提高坚龙胆种子的发芽率。

| Abstract: | Objective] To explore the effects of plant hormone on seed germination of Gentiana rigescens Franch.Method] With the matured seeds of G.rigescens as test materials,effects of GA3,6-BA and IAA on the soaking time and germination status of G.rigescens were studied.Result] Seeds soaked in 200 mg/L GA3+5 mg/L 6-BA+5 mg/L IAA showed the best germination effects and the germination rate reached more than 93%,the germination starting time and germination lasting time were relatively short,germination rate and germination energy were the highest.Conclusion] Based on orthogonal test,effects of plant hormone on seed germination of G.rigescens was in the order of IAA>GA3>soaking time﹥6-BA.Plant hormone treatment could enhance the germination rate of G.rigescens seeds. |
