摘要
在研究的3种藤类的小叶脉里,其维管束鞘大多数都有一层拟内皮层的(endodermoid)外鞘细胞,其内方则多有1至几层厚壁的内鞘细胞。本文在超微结构水平上描述了内、外鞘细胞。最后,讨论了棕榈科及禾本科的一些解剖学文献中的有关问题。
In the small veins o f the three species of rattan,the bundle sheath mayhave two distinct layers of cells.The outer sheath(OS)consists of a layer ofendodermoid cells,While the inner sheath(IS)may have one or several layers of thick-walled cells. Both OS and IS were described at ultrastructural level in this paper.Finally,problems related to the anatomy of the Palmae and Gramineae in the refere nces were discussed.
