| 摘 要： | 黄瓜不同品系的耐热方式存在多样性。与不耐热品系新泰密刺相比 ,高温下品系EP 6通过较高的雌花节率和较强的单性结果能力耐热 ;品系XC 1通过较多的总生长节位和较高的雄蕊及花粉活力耐热 ;品系NY 1则在上述产量形成的诸因子中均有一定优势。在播种后 10～ 50d内 ,黄瓜遭遇高温的苗龄越小 ,产量下降就越多。高温减少黄瓜雌花的效应具有后作效果。

| Abstract: | Different cucumber lines have different heat tolerant ways.Under high temperature,comparing with heat sensitive line Xintaimici,EP 6 have higher female node percentage and parthenocarpic fruit set percentage,XC 1 have more plant node number and higher stamen and pollen heat tolerance, and NY 1 have slight advantage in all aspects above.During the seedling stage 10 to 50 days after sowing,the earlier cucumber seedlings are treated by high temperature,the more yield lose.High temperature can reduce cucumber female flower differentiation even including these nodes. |
