摘要/Abstract

摘要： 利用扫描电镜、叶表皮离析法和石蜡切片法研究了番荔枝科93 种2 变种植物叶片的形态结构。结果表明番荔枝科植物叶片形态结构具有较大相似性, 如叶表面均具有表皮毛, 表皮细胞具有晶体, 气孔器为平列型, 具2～6 个副卫细胞, 仅分布在远轴面, 普遍具有败育气孔器, 叶肉组织中普遍含有油细胞等,但表皮毛的类型, 表皮细胞的形状, 表皮细胞内晶体的类型和形态, 叶肉组织的结构具有明显的属间和种间差异。

关键词: 番荔枝科, 叶形态结构, 比较解剖

Abstract: The leaf form and structure of 93 species and 2 varieties of Annonaceae were comparatively studied with the help of scanning electron microscope, epidermal maceration and paraffin section method . The results showed that the anatomical feathers of the family revealed a remarkable consistency . The leaf surface of Annonaceae are covered with induments, most epidermal cells contained one crystal, the stomatal apparatus are paracytic with 2 to 6 subsidiary cells and distribute on abaxial epidermis, the arrested stomata are found in every species, and the mesophyll tissues contained oil cells. However, the pattern of trichomes, the shape of epidermal cells and the type of crytals in epidermal cells and the structures of mesophyll tissue varies obviously with species and genera.
