摘要
本文对吉林省绣线菊属的９种花粉用光学显微镜和扫描电子显微镜进行了观察和照相，并对它们进行了统计学上的光学测量，详细描述了各种花粉的形态特征，编制了分种检索表，从而为绣线菊属的分类以及该属在蔷薇科中进化上的位置提供了孢粉学方面的资料。
In this paper,the pollen grains of nine;pecies belonging to Spiraea in Jilin province were examined and discribed with optical microscope and scanning electron micro-scope,All of them were measured by statistical method under optical microscope.The pollenmorphofogical characters of Spirace and its nine species were studied and discribed.The keypoint of it was made,so it provided palynology data for classification of Spirace and evolutionposition in Rosaceae.
