不同处理方法对鸟尾花种子萌发的影响

Effects of Different Treatments on Seed Germination of Crossandra infundibuliformis

在西双版纳地区进行鸟尾花引种繁殖试验,研究了不同的培养温度、浸种温度和不同浓度的3种药剂(KH_(2)PO_(4)、GA_(3)和6-BA)浸种处理对种子的发芽率、发芽势和发芽指数的影响。结果表明:45℃清水浸种可促进鸟尾花种子的萌发,在培养箱中变温(25℃/35℃)条件下,发芽情况最好,在同等条件下用200 mg·L^(-1) GA_(3)浸种或100 mg·L^(-1)6-BA浸种处理,鸟尾花种子萌发效果最好。

Experiment of Crossandra infundibuliformis was conducted to study the effect of culture temperature,seed soaking temperature and different concentrations of three chemicals(KH_(2)PO_(4),GA_(3) and 6-BA)on seed germination rate,germination potential and germination index in Xishuangbanna.The results showed that seed germination could be improved by soaking seed in pure water at 45℃and it performs the best under the condition of variable temperature(25℃/35℃)in the incubator;It had the best germination effect when soaked seed with 200 mg·L^(-1) GA_(3) or 100 mg·L^(-1)6-BA under the same condition.
