Abstract
[Objective] To research the application of ethephon to the cross breeding of cucumber.[Method] The hybrid seed yield and quality and other related traits in cucumber were investigated by treating the female parent seedlings with 80,100 and 133 μl/L ethephon for 2-3 times.[Result] Using 80-100 μl/L ethephon twice on female parent of cucumber at the stage of two-leaf and four-leaf seedling could efficiently increase female flower node ratio with lower many female flowers node ratio,and improved average seed yield per plant and thousand seed weight.[Conclusion] The appropriate concentration and times of ethephon had been ascertained,which could be applied in hybrid seed production of Lvdao 3 greenhouse in autumn crop.
