以中林-46杨正常木与应拉木为研究对象，分析比较其在纤维形态、化学组成和制浆漂白上的差异。结果表明在纤维形态上应拉木的双壁厚、壁腔比、木射线比量和纤维比量均高于正常木，而正常木的纤维长宽比、胞腔径、导管比量均大于应拉木；在化学组成上，应拉木的纤维素、苯醇抽出物、1％NaOH抽出物、灰分质量分数均高于正常木，而正常木的半纤维素、综纤维素、木质素质量分数均高于应拉木；在制浆漂白上，应拉木比正常木得率高，卡伯值和白度较低。

With normal wood and tension wood of Populus×euramericana (Dode) Guiner CL.‘zhonglin 46’, the experiment was conducted to study the effects of fiber morphological properties, chemical compositions, pulping, and bleaching.The width of cell wall, runkel ratio, ray proportion, and fiber proportion of tension wood are higher than those of normal wood.How-ever, the fibrous length-width ratio, lumen diameter and vessel proportion of tension wood are lower than those of normal wood.In the chemical composition, the cellulose content, benzene-alcohol extractives, 1%of NaOH extractives and ash of tension woodare higher than those of normal wood.The hemicellulose , holocellulose and lignin of tension wood are less than those of normal wood.In pulping and bleaching for normal wood and tensionwood , the tension wood has higher pul-ping yield, lower Kappa number, and lower brightness of pulp than those of normal wood.
