Wang Qiaomei,Zeng Guangwen,Jiang Youtiao(Horticulture Department of Zhejiang Agricultural University,Hangzhou 310029)  
The environmental conditions under which Momordica charantia seedling grew affected its sex expression.

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 delayed the reproductive growth and weakened the short-day effect. The most suitable environmental conditions for Momordica charantia seedlings were short-day and low temperature
