摘要:

在光学显微镜下观察山茶属金花茶组金花茶系25个分类群的叶表皮形态。结果表明:25个分类群的叶上表皮形态结构相似,气孔仅分布于下表皮。下表皮的细胞垂周壁式样和气孔形状在一些种间存在着明显的差异。分布于不同地貌类型的金花茶种类的气孔密度存在显著差异,分布在石灰岩山地的种类的气孔密度在整体上明显高于分布在非石灰岩山地的种类。

Abstract:

Optical microscope was used to observe leaf epidermis of 25 species of ser. Chrysantha,sect. Chrysantha,Camellia(Theaceae). The results showed that all species had similar morphology structure in upper epidermis of leaf,and stomata were distributed only in lower epidermis. There was remarkable difference in the shape of anticlinal wall and stomata in some species. There was also significant variation in the stomata density of leaf epidermis of Camellia species distributing in different geomorphologic areas. Species disturbing in limestone had higher stomata density in leaf epidermis than species in non-limestone habitat.

Key words: Camellia ser. Chrysantha leaf epidermal morphology
