【摘要】 以不同苗龄全雌系苦瓜X黑-d-d为试材,研究硝酸银不同浓度、不同喷施次数对其诱雄的效果。结果表明,硝酸银诱导全雌系苦瓜X黑-d-d两性花分化的关键时期是三叶期,300mg·L-1硝酸银喷施2次,每次间隔5d的诱雄效果最好。更多还原

【Abstract】 To maximize the production of bisexual flowers of bitter melon(Momordica charantia L.)gynoecious line through chemical induction, different concentrations of AgNO3 were treated at different seedling stages of the gynoecious line X Hei-d-d. The result indicated that the third complete leaf stage was important for the bisexual flower induction with AgNO3 treatments. The optimal AgNO3 concentration was 300 mg·L-1 for X Hei-d-d, and the best results were produced by treating two times with an interval of 5 days.更多还原
