摘要(Abstract)：

为了解杏自交不亲和性强度与授粉受精相关特性的关系,以自交亲和(Self-compatibility:SC)品种凯特(Prunus armeniaca L．cv．Katy)和自交不亲和(Self-incompatibility:SI)品种新世纪(P.armeniaca L.cv．Xinshiji)及凯特×新世纪杂种群体为试材,荧光显微镜观察自交亲和与自交不亲和杏花粉管生长动态。结果表明,授粉后初期,自交亲和性与自交不亲和性的杏花粉都能正常萌发、生长,但是在花粉管生长延伸到花柱1／2以后,自交亲和性的花粉管能顺利进入子房,而自交不亲和性的花粉管多数顶端膨大呈球形,停止向下生长,只有极个别能正常生长到达子房;杂种后代的可溶性蛋白含量和RNA酶比活力,与亲本相比无明显的趋中变异表现,而且在自交亲和与自交不亲和杏之间无显著性差异。

关键词(KeyWords)： 杏;自交不亲和;花粉管;RNA酶活性
