花粉不同保存方法对西瓜授粉效果及种子质量的影响

为筛选出适宜的简易花粉保存方法，采用常温保湿和干燥保存2种方法保存花粉，并对西瓜花粉活力、坐果率、结籽率、种子千粒质量、发芽势及发芽率进行了比较分析。试验结果表明，2种保存方法保存的花粉活力、授粉之后的坐果率、结籽率及种子质量均与对照（活体授粉）差异不显著，说明实践中可采用常温保湿保存和干燥保存方法短期保存花粉，综合分析表明短期常温保湿保存花粉效果较好且省力。

Effects of Different Pollen Storage Methods on Pollination and Seed Quality of Mini-watermelon

In order to screen out the simple storage method for mini-watermelon pollen, we analyzed the pollen viability, fruit setting rate, seed setting rate, thousand seeds weight, germination potentiality and seed germination rate of two different pollen storage methods, keeping pollen wet and dry respectively at normal temperature. The results showed that, taking the two storage methods, the pollen viability, fruit setting rate and seed setting rate had no significant difference with those of the control treatment （pollinating directly）. Therefore, in practice we could keep pollen of mini-watermelon wet or dry in short term at normal temperature. Comprehensively, keeping pollen wet at normal temperature was better for possessing higher seed setting rate and saving time.
