珍稀植物——银鹊树茎、叶解剖学特点的研究

A Study on Anatomic Characteristics of the Stem and Leaf of Tapiscia sinensis, Rare and Precious Plant

银鹊树(Tapiscia sinensis Oliv.)是我国特有的第四纪冰川孑遗植物,又是一种速生树种。本文报道了该种植物茎、叶的解剖学特点。发现了茎组织内有分泌腔分布,维管束排列为一圈,维管柱为管状,叶的远轴面主脉两侧具有花外蜜腺。

Tapiscia sinensis Oliv., a fast growing tree, is a unique plant of the Qua- terary period Glacier in China. The paper deals with anatomy characteristics of the plant stem and leaf. It is discovered that the stem tissue contains secrtory carvity and the vascular cylinder type is siphnostele. There are two tectaries at both sides of the main vein of the abxile. The study of Tapiscia sinensis has a referential value for the plant protection and classification of the plant.
