| 摘 要： | 采用光学显微镜和体视镜，对兰属5种植物（春兰、蕙兰、建兰、寒兰、墨兰）的叶结构特征（叶脉结构、叶表皮结构、解剖结构）进行了观察和测量。结果显示，兰属5种植物的叶脉结构相似，叶表皮结构和解剖结构存在较大差异，其中最主要的差异是皮下纤维束的多少和边缘角质层锯齿形态。依据叶结构特征聚类分析结果，5种兰可分为春兰组、建兰组和墨兰组3组。本研究表明叶结构特征对兰属5种植物的分类具有重要意义。

| Abstract: | Leaf architectural characteristics (vein architecture, epidermal architecture, and anatomical architecture) of five species of Cymbidium (Cymbidium goeringii (Rchb. f.) Rchb. f, C. faberi Rolfe, C. ensifolium (L.) Sw., C. kanran Makino, and C. sinense (Jackson ex Andr.) Willd.) were observed and measured using optical microscopy and stereomicroscopy. Results showed that among the five plants, vein architectures were similar but there were significant differences in the epidermal and anatomical architectures, mainly in the quantity of fiber bundles and structure of stratum corneum edge. Based on cluster analysis of the leaf structure characteristics, the five species of orchid could be divided into C. goeringii formation, C. ensifolium formation, and C. sinense formation. This study showed that leaf structure characteristics have great significance for the classification of these five species of Cymbidium. |
