- 摘要:
- 以“D0716”黄瓜植株为试材，研究了不同温度条件下黄瓜鲜雄花保存花粉、直接保存花粉和贮藏花蕾对花粉活力的影响。结果表明：黄瓜花粉活力随贮藏时间延长而降低；低温可以延长黄瓜花粉的寿命，但不利于黄瓜的开花和散粉；4℃下贮藏黄瓜鲜雄花花粉寿命比CK延长84 h，且萌发率降低程度最小；直接保存花粉比鲜雄花保存花粉的花粉寿命短；与15℃相比，4℃贮藏花蕾的花粉活力保持的时间要长，但低温不利于开花散粉，所以在授粉前要将低温贮藏花蕾提前放在常温（25℃）一段时间以加速雄花的开放和散粉。
- Abstract:
- With ‘D0716’ cucumber as test materials，the effect of different temperature conditions on fresh cucumber male flower storage，directly pollen storage,buds storage to pollen viability were studied.The results showed that the cucumber pollen viability decreased with the storage period prolonged.The low temperature could prolong the life of the cucumber pollen，but was not conducive to the cucumbers flowering and shedding.Under 4℃ storage,fresh cucumber male flower pollen life extend 84 hours compared to the control (25℃)，and the reduction of the germination rate was minimum.Pollen viability under directly saved pollen was shorter than fresh male flowers storage.The time of storage bud pollen viability remained to be long under 4℃ compared to 15℃，but the low temperature was not conducive to flowering shedding，so before pollination buds should be storaged in advance in the room temperature (25℃) for a period of time to accelerate the male flowers open and loose powder.
