黄连木与紫油木木材解剖特征比较研究

摘要

利用体视显微镜和生物显微镜,对黄连木和紫油木的木材构造特征进行了比较解剖研究.结果表明:两者的宏观构造特征在材色及管孔的分布类型、大小、排列有较大的差异.微观构造特征的差异主要表现在管孔的组合方式及木射线的大小;解剖分子的差异主要表现在导管分子平均弦向直径、木纤维分子腔径及壁腔比、轴向薄壁细胞分子长度方面,其余解剖特征差异不明显.%Using stereo and biological microscope, a research on comparative anatomy was carried out on the characteristics of timber structures between Pistacia chinensis and P. vueinmannifolia. The results were as follows. Great differences existed in their gross structures in terms of color and the arrangement pattern and diametre of pore. Differences in microscopic structures were mainly manifested in the combination of pore and the size of xylem ray. In the anatomy element, differences were mainly in average tangential diameter of vessel element, cavity length and ratio of wall of wood fiber element, the length of axial parenchyma cell element, while other anatomical characteristics were not obvious.
