云南沉香和白木香的木材结构比较解剖学研究

Preliminary Study on Timber Structure of Aquilaria yunnanensis

通过显微和亚显微解剖观察方法,对云南沉香和白木香的木材结构进行初步研究。结果表明,云南沉香的木材由内函韧皮部、木射线、管孔、木纤维等组成。内函韧皮部呈岛式均匀分布,可见大量的长方体晶体;管孔以复管孔、单管孔的形式存在;木射线为异性Ⅲ型。说明云南沉香与白木香的木材结构基本一致。

Taking Aquila ria yunnanensis and A. sinensis wood as experimental material, through microscopic and submicroscopic anatomical observation, their timber structure was studied. The result shows that the timber structure of A. yunnanensis is consist of the included phloem, wood ray, pipe hole and wood fiber. A transverse section shows that the many of the included phloem （foraminate type） is scattered in the xylem, There are lots of rectangular crystals in the included phloem; Tube holes can be divided the multiple pores, single hole two kinds; The xylem rays is belonged to heterogeneous III. This study shows that the timber structure ofA. yunnanensis and A. sinensis is similar basically.
