| 摘 要： | 利用光学显微镜和扫描电子显微镜对中国卫矛属(Euonymus L.)24种以及沟瓣属（Glyptopetalum Thw.）3种植物的叶表皮微形态特征进行了观察研究，测量并统计了气孔器长宽比、密度和气孔指数。结果显示，两属植物叶表皮微形态特征基本一致：叶上、下表皮细胞形状多为多边形，垂周壁平直-弓形；气孔器通常仅分布在叶下表皮；均具有无规则型气孔器，部分种还具环列型气孔器。扫描电镜下角质膜纹饰、表皮细胞界限及气孔特征在一些种间存在差异，可以作为区分部分近缘种类的参考依据。

| Abstract: | The leaf epidermal characteristics of 24 species of Euonymus and 3 species of Glyptopetalum in China were investigated using light microscopy(LM) and scanning electron microscopy(SEM).The stomatal ratio of length to width,density and index were measured.The results revealed that the epidermal structure is of the same type in the two genera: most of adaxial and abaxial epidermal cells are polygonal shapes,and their anticlinal walls are mainly straight-arched;The stomatal apparatuses only present on the abaxi... |
