摘要: 对采自75 个不同居群的塞威氏苹果(Malus sieversii (Ldb.)Roem)的花粉形态进行了观察。结果表明:塞威氏苹果花粉萌发孔为三孔沟类型, 外壁具条纹状纹饰, 条纹间常具小穴或穿孔。根据外壁纹饰的差异将塞威氏苹果花粉划分为六个类型。同时根据花粉资料, 探讨了塞威氏苹果的某些分类学和系统学问题。

Abstract: The pollen morphology of Malus sieversii from 75 different populations were observed and reported in the present paper. The results showed that pollen morphology and exine characteristics could provide important significance to the taxonomy of the species. The pollen grains of Malus sieversii are 3-colporate type and its morphology and exine characteristics showed minute difference among different populations, according to which the pollen grains of the species can be grouped into 6 types. Some taxonomic and systematic problems were also discussed in the paper.

Key words: malus sieversii, population, pollen morphology
