| 摘 要： | 利用ANKOM公司的A2000i型全自动纤维分析仪即滤袋法进行测定，研究了20个水曲柳种源的14年生多点试验林的木材纤维素、半纤维素和木质素含量的变异情况。结果表明，同一试验点20个水曲柳种源纤维素、半纤维素和木质素差异显著。其中，海林、西丰和带岭3个种源水曲柳的半纤维素、纤维素和木质素与其他种源间差异显著，取材于帽儿山和带岭两试验点的相同种源水曲柳的3性状差异亦显著。水曲柳的半纤维素含量、纤维素含量和木质素含量与种源地、试验点显著相关。水曲柳的半纤维素含量、纤维素含量和木质素含量在种源间、地点间、种源和地点交互作用差异均显著。

| Abstract: | The variations of the contents of wood cellulose,hemicellulose and lignin in the samples of 14-year-old Manchurian ash from 20 provenances that were cultivated in different sites were investigated.Automatic fiber analyzer,type A2000i,made by Ankom Company was used to conduct the measurement.The results showed that within the same cultivation site,significant differences in the contents of cellulose,hemicellulose and lignin among 20 provenances were observed.Among them,the contents of cellulose,hemicellulose and lignin in provenances of Hailin,Xifeng and Dailing were significantly different from other provenances.Within the same provenance,samples collected from different cultivated sites also exhibited significant differences in the contents of 3 components.The contents of cellulose,hemicellulose,lignin were significantly correlated with provenances and cultivation sites.Significant differences were also observed in the interactions between provenaces,cultivation sites,as well as between provenance and site. |
