台灣省產藤亞科藤材微細構造之研究（I）台灣黃藤之微細構造

本研究乃利用Bausch & Lomb Ltd. Nanolab 2100 SEM研究臺灣黃藤的微細構造，得結果如下：臺灣黃藤具散生中心柱，僅有一層表皮細胞，臘質層很厚，角質層不明顯，皮層窄狹，纖維鞘為間斷型，維管束散生，近藤皮者體積小，向藤心者體積大，早成韌皮部不易看到，但晚成韌皮部、早成木質部及晚成木質部均明顯易辨。晚成韌皮部的纖維冠為半月形，其纖維的壁具有較多的層次，各層的厚度差異不大。基本組織的柔壁細胞形態變化大，許多細胞腔及細胞間隙中常有不同形狀的單晶體、簇晶體、或晶列，導管腔、纖維腔、或纖維間隙中偶爾亦有。柔壁細胞間有分泌溝、分泌溝外側有一層鞘狀細胞。

Rattan are belonged to Lepidocaryoideae of Palmae. They are abandent in Southeast Asia. But there are only one genus and three species in Taiwan. In this study, Yellow Rattan Palm was chosen and observed with Bausch & Lomb Ltd. Nanolab 2100 SEM. The samples were cut from the cane, then softed, trammed, dehydrated, critical point dried, and put it into SEM for observing and recording. The following conclusion can be drawn. (1) Yellow Rattan Palm has an atectostele. (2) Its epidermis consists of a single layer of cells, with a thicker wax layer and inconspicuous cuticular layer. (3) Its cortex is very narrow (only a few layers). (4) Its fiberous sheath is interruptional type. (5) Its vascular bundles disperse in the ground tissue. Which consist of an obliterated or inconspicuous protophloem, a conspicuous metaphloem, protoxylem, and metaxylem. (6) The wall of fiber cap are multilayer which are uniform in the thickness. (7) The parenchyma of ground tissue vary in shape, size and arrangement. (8) The crystals of various forms, such as solitary, druse and crystal bearing fiber, are often present in some lumina and intercellular spaces. (9) The secretory canals sometimes present among the ground tissue.
