利用扫描电镜对降香黄檀Dalbergia odorifera T. Chen木材的组织构造进行了系统分析，重点分析了不同类型细胞的纹孔的典型特征。降香黄檀木材导管壁上的纹孔为互列式，附物非常丰富；轴向薄壁细胞壁上为单纹孔，个体较大而数量较小，成组聚集分布，3～5个一组呈猫爪或花瓣状。木材纵切面上，轴向薄壁组织中常见似“分室含晶细胞”，但经X-射线能谱仪分析表明，这种“分室含晶细胞”中的块状物并不是传统认为的草酸钙等无机盐物质，其主要组成元素为碳和氧，由此可初步认定这种似“分室含晶细胞”中的块状物为树胶类物质。%The wood structure of Dalbergia odorifera T. Chen was systematically analyzed with the scanning electron micro-scope, the typical characteristics of the wood pits of different type woods were earnestly analyzed. It was found that the wood pits on the vessel wall of Dalbergia odorifera wood presented in the form of inter-row, the attached materials were very rich; the pits on the axial parenchyma cell walls belong to single pits with larger body but less in number compared to the vessel pits, they aggregated into groups of 3~5 and looked like cat’s paws or petals;on the longitudinal sections, something like“compartment crystal cells”in axial parenchyma was commonly found, but the lumps in the“compartment crystal cells”are not inorganic salts such as calcium oxalate, as traditionally recognized. The results of X-ray energy dispersive spectroscopy analysis show that the composition elements of the lumps were mainly carbon and oxygen. According to this, it may be concluded that the lumps in the“compartment crystal cells”belong to the gum substances.
