| 摘 要： | 本文通过两年三点次，用１０种激素不同浓度，在父本始穗至齐穗期喷施的试验结果。初步筛选出乙稀利１０００～２０００ｐｐｍ与ＮＡＡ１００～２００ｐｍ，有一定的推迟父本花时的效应，对异交结实率不仅无影响，尚似有提高的作用，其处理后授粉结实的Ｆ１生长发育正常。

| Abstract: | Ten kinds of hormone with various concentrations were sprayed on male parent plants during heading penedin 1992 and 1993,amount to three localities.The initial results showed that 1000 to 2000 ppm ethephon and 100to 200 ppm NAA could put off male P8rent flowering time and had no harmful effects to cross fertility rate.The F1 plants of treated male parent grew normally although there are some problems to be solved. |
