竹柏属叶角质层微形态的观察

Cuticle Micromorphology of Nageia

摘要: 利用扫描电镜对竹柏属(Nageia)6种植物叶角质层内外表面进行了细致的观察。发现竹柏属植物叶角质层特征具有明显的种间差异,利用这些差异能够将形态上较难区分的类群区分开。同时,根据叶角质层内表面特征,支持将台湾竹柏(Nageia nankoensis)和窄叶竹柏(Nageia formosensis)从广义竹柏中分离成两个不同种的观点。

Abstract: Cuticle micromorphology of leaves from 6 species of Nageia was studied with scanning electron microscope.Observation revealed that there exist distinct differences among different species in the internal features of leaf cuticle in Nageia.At the same time,cuticle micromorphology indicates that N.nankoensis and N.formosensis should be divided into two separate species.
