摘　　要：Leaf epidermal fingerprints of six species of Rhododendron （ Rh. Aureaum, Rh. dauricum, Rh. micranthum, Rh. Mucronulatum, Rh. Redowskianum, Rh. schlippenbachii） were observed by optical microscope with nail polish expression method in Key Laboratory of Forest Plant Ecology of Ministry Education China in Northeast Forestry University in 2004. The leaf morphological features including of stomata types, characters of guard cells, subsidiary cells in lower epidermis were observed. And ordinary cells （in shape and anticlinal walls feature） as well as the trichomes in both sides of the leaves are described in detail. The results showed that there were three types of stoma in six investigated Rhododendron species, from which Pericytic stomata type exists in three species （Rh. dauricum, Rh. micranthum, and Rh. mucronulatum）, Anomocytic stomatal type in Rh. Redowskianum, Diacytic stomata type in Rh. aureaum and Rh. schlippenbachii. The subsidiary cells of the Pericytic and Diacytic stomata type are different in shape and surface feature between the species, respectively. The ordinary epidermal cells show a variety from quadrangular to hexagonal, polygonal or irregular in surface view, the anticlinal walls are straight or sinuose. Trichomes （gland scales） are present in the both of the leaf sides in three species （Rh. dauricum, Rh. micranthum, and Rh. mucronulatum）. All of these detail leaf features show specific specificity of leave finger print for 6 rhododendrons.长叶杜鹃花属的六种的表皮的指纹(Rh。Aureaum， Rh。dauricum， Rh。micranthum， Rh。Mucronulatum， Rh。Redowskianum， Rh。schlippenbachii ) 被光显微镜在 2004 在东北林地大学里在部教育中国的福雷斯特植物生态学的关键实验室与指甲光泽表示方法观察。stomata 类型包括的叶形态特征，保卫细胞的人物，在更低的 epidemis 的辅助房间被观察。并且平常的房间(在里面形状；背斜的墙特征) 详细象在叶子的双方的毛状体一样被描述。结果证明有在六调查杜鹃花属种，从 Pericytic， stomata 类型在三种存在的气孔的三种类型(Rh。dauricum， Rh。micranthum，；Rh。mucronulatum ) ，在 Rh 的 Anomocytic 有气孔的类型。Redowskianum， Diacytic stomata 录入 Rh。aureaum；Rh。schlippenbachii。Pericytic 的辅助房间；Diacytic stomata 类型在形状是不同的；在种类之间的表面特征分别地。平常的表皮的房间显示出一个变化从对在表面六角形、多角形或不规则的看法四角形，背斜的墙是直的或 sinuose。毛状体(腺规模) 在在三种的叶方面的两个是在场的(Rh。dauricum， Rh。micranthum，；Rh。mucronulatum ) 。这些详细，叶展示的所有为 6 杜鹃属的植物显示出叶子手指出版的特定的特性。
