摘要
对北方六省六个地区天然林中的山杨(Populus davidiana)木材解剖、物理力学性质、化学成分进行的研究。结果表明:六个种源的山杨木材解剖特征、化学成分无明显差异,物理力学性质存在不同程度的差异。此外,还对六组山杨的胶质纤维、侵填体,髓斑进行了研究。
A study on the wood properties of natural growth poplar (Populus davidiana) from six northern provinces of China has been done. The results of morphology of fibre, proportion of different tissues, physical and mechanical properties, chemical composition have been studied. The stems of six provenience poplar contained much gelatinous fiber, tylesis and pith fleck. The physical and meehanical properties of six provenances changed within different groups. This poplar is a good pulping material.
