| 摘 要： | 研究了赤霉素(GA3)和发芽温度对圆叶牵牛种子萌发的影响。结果表明:28℃较高温度处理圆叶牵牛种子,发芽指数和发芽率高于23℃较低温度处理,但未达到显著水平。200mg/L GA3浸种可显著提高圆叶牵牛种子的发芽率和发芽指数,发芽起始时间和终止时间也有所提前。

| Abstract: | The effects of gibberellin(GA3) and germination temperature on Pharbitis purpurea(Linn.) Voigt seeds germination were studied.The results showed that the germination index and germination percentage of Pharbitis purpurea(Linn.) Voigt seeds were higher under 28℃ than 23℃,but the difference wasn’t significant.The germination percentage and germination index of Pharbitis purpurea(Linn.) Voigt seeds were improved observably,and starting time and the final time of the seeds germination were ahead of time with 200 mg/L GA3 soaking seed. |
