以黄枝润楠天然次生林木材为研究对象,观察分析黄枝润楠木材的宏观构造特征和显微构造特征.结果表明:黄枝润楠为散孔材,管孔肉眼下可见至明显,单管孔和短径列复管孔为主(通常2~4个),稀管孔团;部分导管内含侵填体.轴向薄壁组织肉眼下可见,主为环管束状,偶见稀疏环管状.木射线肉眼下可见,径面射线斑纹可见;木射线非叠生,射线组织为异Ⅲ及异Ⅱ型,单列射线甚少,高2~8细胞;多列射线宽2~3细胞(以2列为主),高4~39细胞,多数为8~27细胞,油细胞数多;管间纹孔互列,偶见对列;单穿孔,穿孔板倾斜明显,偶见梯状穿孔;木材具分隔木纤维.
Machilus versicolora S. Lee wood from natural secondary forest were taken for study by measuring and analyzing the macrostructure and microstructure characteristics. The results showed that M. versicolora was diffuse-porous wood and its pores could be seen or slightly seen under naked eye which were mainly solitary pore and short diameter radial multiple pore (usually 2-4), rarely were vessel cluster; and a portion of the vessel had tylosis. Axial parenchyma were visible under naked eye while mainly of them were vascentric, rarely were scanty paratracheal. Wood ray were also visible under naked eye and ray fleck could be seen on the radial section;wood ray were non-storied, generally were typeⅢandⅡ, the single ray was few consist of 2-8 cells;the multi-seriate ray, containing a lot oil cells, were 2-3 cells wide ( mainly 2) , 4-39 cells high( mostly 8-27);intervessel pit mostly alter-nate and opposite pit occasionally appeared;perforation vessel had simple perforation plate while the plate significantly tilted, sca-lariform perforation occasionally appeared;septate wood fiber was found.
