| 摘 要： | 西双版纳黄瓜是分布于我国西双版纳地区的一群独特的黄瓜资源,由于其光周期敏感的特点,育种应用较为困难。本试验采取8h/16h的短日照条件,研究了短日处理0、10、20、30、40d对西双版纳黄瓜开花的影响。结果表明,短日处理有显著的促雌效应,第1雌花节位提早,雌花数增多,并且随着短日处理天数的增加该效应愈强。检测分析表明短日处理诱导出的雌、雄配子均活力正常,可用于育种研究。

| Abstract: | Xishuangbanna cucumber (Cucumis sativus L .var.xishuangbannesis Qi et Yuan) is a group of unique cucumber germplasm located in Xishuangbanna region.Due to its sensitivity to day length for flowering,it has been not easy to use it in breeding.This experiment was carried out to study the effect of short-day treatments(8 h/16 h for 0,10,20,30,40 days) on flowering of Xishuangbanna cucumber.The results showed that short-day treatments significantly promoted female flowers.The first node of female flower was lower,and the number of female flowers increased with increase of short-day treatment time.Both the male and female flowers induced by short-day treatment had normal viability. |
