温度和光周期对苦瓜性别表现的影响

苦瓜苗期所处的环境条件会影响其性别表现，株洲长白和英引苦瓜品种的光周期反应表现为短日效应，即短日使植株的发育提早，并促进雌性发育，长日的效果恰好相反。苦瓜苗期短日处理时期以出苗至６片真叶（苗龄２０天）为宜。低温可以增强短日效应，高温则使苦瓜的生殖生长推迟，并削弱短日效应，短日低温是苦瓜苗期最适宜的环境条件。

Effects of Temperature and Photoperiod on Sex Expression of Momordica Charantia

The environmental conditions under which Momordica charantia seedling grew affected its sex expression. Both varieties“Zhuzhou Changbai”and“Yingyin”were short-day plants,the short day length resulted in earlier plant development and more female flowers. The short-day treatment period of Momordica charantia seedlings should be from the day when the seedlings were first emerged to the day when the sixth leaf appeared(at age of 20 days). Low temperature enhanced the short-day effect,while high temperature dela...
