| 摘 要： | 为紫苏杂交育种提供参考,对紫苏的开花期(花蕾期、初开期、盛开期、凋谢期)进行定位观测,采用醋酸洋红染色法和联苯胺-过氧化氢法对紫苏的花粉活力和柱头可授性进行测定。结果表明:花前6h的花粉活力最高,为82.76%;柱头在花前6h至花后3h内具有较高的可授性。

| Abstract: | The pollen activity and stigma receptivity of P.frutescens are observed and determined by carmine acetate dyeing and benzidine-hydrogen peroxide methods during anthesis (bud stage, early flowering stage, full flowering stage and wither stage) to provide a reference for crossbreeding of P.frutescens.Results: The pollen activity of P.frutescens is the highest (82.76%) at 6 h before the anthesis.The stigma of P.frutescens has the higher receptivity during the period of 6 h before anthesis and 3 h after anthesis. |

| Keywords: | Perilla frutescens flowering dynamic change pollen viability stigma receptivity |
