　　以引种植物大花百子莲为对象，对其在引种地的花粉活力、柱头可授性进行了研究，探讨了两者与授粉成功的关系。结果表明：大花百子莲花粉萌发的最佳培养基为10％蔗糖＋0．1％ H3 BO3＋0．2 g? L-1 Ca（NO3）2；随着开花进程的不断深入，花粉活力不断下降，始花期的花粉活力接近80％，末花期花粉活力只有3％左右；花粉在4℃条件下存活时间约为7 d，25℃条件下存活时间为5 d，而在35℃条件下存活时间只有2 d；大花百子莲花粉在开花当天已具有萌发能力，而柱头在开花第2天具有可授性，因此大花百子莲存在雌雄异熟现象。

We investigated the pollen viability and stigma receptivity of A.praecox ssp.orientalis‘Big Blue’ in Shanghai, Chi-na, and analyzed the influence of pollen viability and stigma receptivity to reproduction.The best composition of medium is 10%sucrose+0.1%H3 BO3+0.2 g? L-1 Ca(NO3 ) 2 .Pollen viability gradually reduces with the flowering process.Pollen viability is 80%at initial time of florescence and the value is 3%at the end of florescence.Survival time of pollen is seven days in 4℃.The value is five days in 25℃and two days in 35℃.Pollen has the germination ability at the first day of flowering and stigma has receptivity ability at the next day of flowering.Therefore, A.praecox ssp.orientalis‘Big Blue’ is dichogamy.
