摘 要:以东非黑黄檀(Dalbergia melanoxylon)木材为研究对象,观察分析木材的宏观构造和显微构造,测定分析其各类细胞的构造特征参数。结果表明,东非黑黄檀木材生长轮、波痕较不明显,结构细,木材纹理较直;心材带深色条纹,黄褐至紫褐色;散孔材,管孔组合类型以单管孔为主,少数复管孔,管孔内含深色树胶;轴向薄壁组织傍管型翼状、星散聚合状;木射线为细木射线,木射线类型主要为同形单列,少数同型多列;在肉眼下不明显;木纤维叠生,腔小壁厚;具分室含晶细胞。组织比量最大为木纤维占80.09%,最小为分室含晶细胞占0.12%。根据1976年国际照明委员会推荐的均匀颜色空间CIE(1976)L*a*b*和孟塞尔色度空间测定说明,东非黑黄檀木材以低饱和度的红、黄色调为主,颜色较深沉。通过对东非黑黄檀宏观、微观结构特征等进行研究,为识别、利用东非黑黄檀提供参考。In this paper,taking the Dalbergia melanoxylon wood as the research object,the macrostructure and microstructure of the wood were observed and analyzed,and the structural characteristic parameters of various cells were measured and analyzed.The results showed that the Dalbergia melanoxylon wood growth rings and ripple marks were less obvious,fine structure and straight texture.Heartwood had dark stripes and was yellowish-brown to purplish-brown.For loose hole material,pipe hole combination type was mainly single pipe hole,a few compound pipe hole,and pipe hole contained dark gum.Axial parenchyma was partubular wing and scattered polymerization.The wood rays were fine wood rays,and the main types of wood rays were homomorphic single row and a few homomorphic multiple row.It was not obvious to the naked eye.Wood fiber was stacked,cavity was small and wall was thick.It had compartmentalized crystalline cells.The highest tissue ratio was 80.09%of wood fiber,and the lowest was 0.12%of compartmentalized crystalline cell.According to uniform color space recommended by the International Lighting Commission 1976 CIE(1976)L*a*b*and Munsell chromatic space,Dalbergia melanoxylon wood is mainly red and yellow with low saturation,and the color is deep.Through the study of macrostructure and microstructure characteristics of Dalbergia melanoxylon wood,it provides a reference for identification and utilization of Dalbergia melanoxylon.
