授粉温度对黄瓜网室采种产量的影响

Effecfs of Temperature During Pollination on Cucumber Seed Yield Under Net House Conditions

授粉温度的高低，对黄瓜制种的质量和产量具有重要影响。通过试验表明，黄瓜采种的适宜授粉温度为２０～３１℃之间，最适温度为２７～３０℃；在１８～２０℃和３１～３３℃时，也能进行授粉，但效果较差；当气温处于１８℃以下或３３℃以上时，就不应再进行授粉工作了。

The effect of temperature during pollination on cucmber seed production was studied in this paper.The results indicated that temperature during pollination had a crucial influence on cucumber seed quality and yield.The s uitable temperature during pollination for cucmber seed production was between 20℃ and 31℃.The optimum temperature for pollination was 27℃～30℃.At temperatures of 18℃～20℃ or 31℃～33℃,pollination was still possible but less effective.When temperature is under 18℃ or above 33℃,pollination work should be terminated.
