AgNO₃및 Ethrel 處理에 따른 호박의 性表現 및 生育特性
郭秀年,徐明基 목포대학교 자연자원개발연구소 2000 자연자원연구 Vol.3 No.-
The possibility of AgNO3 and ethrel(2-chorophosphonic acid)treatments to regulate sex expression of Cucurbita for hybrid seed production was investigated. Treatments of Cucurbita plants with ethrel induced an earlier female flowers and greater production of female flowers, while those with AgNO3 induced a greater production of male flowers and late female flowers. Treatment with high concentration of ethrel reduced the growth but that with AgNO3 showed little effects of the growth. The effects of AgNO3 and ethrel on sex expression in Cucurbita varied among the species and cultivars. It seems due to the difference in the femaleness of species and cultivars investigated.
