摘要
通过茎、叶显微结构的解剖观察，表明小獐毛（Aeluropuslittoralis（Gouan）Parl．）与其它盐地植物相比，具有含晶细胞数目多，叶片中鞘细胞伸展区发达，茎、叶表皮细胞外壁硅质化明显，叶栅栏组织发达，而机械组织不发达等特点。结合小獐毛自然生境、群落特征，初步分析了其外部形态、解剖结构与盐地生境的适应关系。
It is shown from anatomical observation of the microscopic structure in stems and leaves that Aeluropus littoralis (Gouan) Parl. have several characteristics as follows:more crystal cells,well-developed bundle sheath extension zone in blades,significant silicification of external wall in epidermis cells,well-developed palisade tissue in blade but undeveloped mechanical tissue. Associated with the natural habitats and, community structure,the adaptive relationships of the enternal morphology and anatomical structure of the species to saline habitats was primarly analysed in this paper.
