本科毕业论文 商品材柚木、白脆皮的树种识别 及解剖构造研究 学 院：材料科学与艺术设计学院 专 业：材料科学与工程 学 号：080813173 姓 名： 指导教师： 职 称：副教授 论文提交日期：二Ο一二年六月 摘 要 论文针对木材的识别与利用，采用生物显微镜、定量分析、显微图像分析等测试技术和分析手段，对商品材柚木和白脆皮的解剖构造进行分析和研究，取得了构造照片、组织比量等指标，确定了树种名。研究结果表明：商品材柚木为马鞭草科（Verbenaceae Jaume St-Hil.），柚木属（Tectona L. f.），柚木（T.grandis L. f.）。半散孔材，管孔组合为单管孔和少数径列复管孔（2个），散生，平均7个/ mm2，单穿孔。木纤维含量67.02%，平均长度1021.55μm。射线组织同形多列（2～5个）。商品材白脆皮为海桑科（Sonneratiaceae Engle. Gilg），八宝树属（Duabanga Buch-Ham）。散孔材，管孔组合为单管孔和少数径列复管孔（2个），散生，平均3个/ mm2，单穿孔。木纤维含量68.29%，平均长度1337.06μm。射线组织同形单列及异形单列。 关键词：柚木 白脆皮 解剖构造 组织比量 木材识别 Abstract The paper focus on the identification and utilization of the wood, which analysis and research the anatomical structure of Youmu and Baicuipi, by using special testing technology and analytical tools such as biological microscope, quantitative analysis, microscopic image analysis.Through the test construction photos, tissue proportion and other indicators were obtained, and confirm the tree species names. The results show that: Merchantable timber Youmu is Verbenaceae Jaume St-Hil., Tectona L. f., T.grandis L. f..Youmu is semi-diffuse porous wood, combined as solitary pore and a few multiple pore（double cells）of the pore complex, scattered，the average number of pore distribution is 7/mm2. Single perforation. The fiber content is 67.02% , the average length is 1021.55μm.Ray tissue-type is homogeneous homocellular multiseriate rays（2～5 cells）.Merchantable timber Baicuipi is Sonneratiaceae Engle. Gilg, Duabanga Buch-Ham.Baicuipi is diffuse-porous wood, combined as solitary pore and a few multiple pore（double cells）of the pore complex, scattered，the average number of pore distribution is 3/mm2.Simple perforation. The fiber content is 68.29%,the average length is 1337.06μm.Ray tissue-type is homogeneous homocellular uniseriate ray and heterogeneous heterocellular uniseriate ray.
