| 摘 要： | 研究了不同贮藏温度对黄瓜新鲜雄花和花蕾花粉活力的影响。结果表明:5～25℃范围内,随着贮藏温度的降低黄瓜花粉寿命延长,5、10、15℃分别较常温(25℃)的花粉寿命长60、44、34h;低温贮藏花蕾能有效地延长花粉寿命,以在傍晚(约18:00)采摘第2天将开放的大花蕾为贮藏材料较好;5℃低温下花粉活力持续时间最长,但因低温不利于雄花开放和散粉,所以在授粉前将5℃低温贮藏的花蕾放在常温(25℃)下1～2h以加速雄花的开放和散粉。

| Abstract: | Effects of fresh male flower and flower buds storage temperature on cucumber pollen viability were studied.The results indicated that pollen survived longer in lower temperature,pollen viability in 5,10 and 15 ℃ were 60,44 and 34 h longer than that in 25 ℃ respectively;collecting male flower buds late in the afternoon(about 18:00)is better than that in earlier time;flower buds at 5 ℃ storage maintained the longest pollen viability,but was not better for flowering and pollen dispersion,so treating flower bud... |
