摘  要:
以四川紫楠(Phoebe sheareri)活立木为研究对象,通过观察紫楠木材宏观及微观构造,测定管孔、木纤维等结构的参数,分析木射线、轴向薄壁细胞、纹孔、结晶体等的构造特征,对紫楠木材的构造特征进行客观的分析和评价。结果表明:都江堰紫楠宏观上表现为边材呈淡灰色,心材淡褐色,心边材区分明显,味苦;微观上表现为散孔材,导管横切面多为卵圆形,薄壁细胞和射线细胞内含油细胞,射线组织为异形Ⅱ型或异形Ⅲ型,细胞内及细胞间隙含有大量球状树胶类物质,木射线细胞内存在块状含钙物质。

摘  要:
With Phoebe sheareri standing timbers growing in Sichuan Province,we studied the wood structural characteristics of Phoebe sheareri through observing macro and micro wood structure,measuring the anatomic parameters,and analyzing the morphology,arrangement and composition of wood ray,longitudinal parenchyma,pit,and crystal. P. sheareri sapwood takes on pale grey in macroscopic scale,which is quite different from heartwood pale brown. P. sheareri wood is with a bitter taste. In microscopic scale P. sheareri is diffuse-porous wood,cross section of catheter are mostly oval,parenchyma cells and ray cells contain oil cells,ray tissues are heterogeneous type II or type III,lots of spherical Gum class materials exist in cells and between cells,and block calcium materials can be seen in wood ray cells.
