摘要/Abstract

摘要： 利用光学显微镜和扫描电镜对11 种珍珠菜属植物种皮微形态特征进行了研究。根据种皮微形态特征, 可以明显的划分为两种类型, 即黑腺珍珠菜型和金爪儿型。珍珠菜亚属的7 种植物均属于黑腺珍珠菜型, 黄连花亚属的4 种植物均属于金爪儿型。种皮微形态特征支持以雄蕊群的构造为主要依据的属下分类系统, 在亚属级水平具有重要的分类学意义。

Abstract: The microcharacteristics of seed surface in Lysimachia of the family Primulaceae were investigated by light microscope (LM) and scanning electron microscope (SEM). Based on the morphological characters of seed epidermis cells, the seeds coats can be divided into two distinct types, Heterogenea-type and Grammica-type. 7 species of Subgen. Palladia of China all belong to Heterogenea-type, and 4 species of Subgen. Lysimachia of China to Grammica- type. The results show that there are remarkable differences in the morphological features of seed surface between subgen. Palladia and subgen. Lysimachia, which might have significant taxonomic implications at subgenus level .
