| 摘 要： | 利用光学显微镜观察了十字花科8种植物的叶表皮形态。结果表明,菘蓝属3个种与鸟头荠族的5个单种属植物叶的上下表皮细胞均存在着多边形和不规则形的特征,差异不显著。8种材料的气孔器类型表现的非常一致,即上下表皮的气孔器类型均为不等细胞型并有少量的无规则型。在气孔的大小、气孔指数和气孔密度上表现出一定差异,但没有明显的规律。通过研究证实了菘蓝属与鸟头荠族的亲缘关系较近。

| Abstract: | Leaf epidermis of 8 species of plant,which belong to Brassicaceae have been examined under light microscope（LM）. The main conclusions are as follows：the shapes of leaf epidermal cells in 3 species of Isatis and 5 single genera of Eulidieae were usually polygonal or irregular. There were no significant differences in each other. The type of stomatal apparatuses of the upper epidermis and the lower epidermis had better consistency,which was mainly anisocytic, rarely anomocytic. The stomatal size, the stomatal index and the stomatal density showed some differences,but no significant regularity. The study has verified that Isatis was closely related to Euclidieae. |
