| 摘 要： | 在扫描电子显微镜下观察了浙江产的12种(变种)榕属植物的叶表皮和瘦果形态.结果表明:叶下表皮均有气孔器,上表皮均未发现气孔器;气孔外拱盖内缘呈浅波状、啮齿状或平滑;叶表皮角质膜具浅波状细条纹、深波状粗条纹或具蠕虫状条纹;瘦果分为4个类型:脊条状纹饰,皱波状纹饰、乳头状纹饰和浅波状纹饰.上述特征在不同种之间都有一些差异,这些差异可作为区分种和变种的辅助特征.

| Abstract: | Morphology of leaf epidermis and achene of 12 species (including varieties)in Ficus of Zhejiang was examined under scanning electronic microscope (SEM). The results show that stomata are found in all abaxial epidermis, but not in adaxial epidermis; that the inner margin of outer stomatal rim is sinuotate, erose or smooth; and that the cuticular membrane of leaf epidermis is with fine striated shallow wave, coarsely striated deep wave or worm-striated. The achene is divided into four types: Ridge-form. Wrinkled-wave. Nipple-form and Shallow wave. All the differences can be used as subsidiary characteristics to distinguish species or varieties from one another and have some systematic significance to the taxonomy of Ficus. |
