借助于扫描电子显微镜对东北重要阔叶树环孔材水曲柳、光叶春榆、黄波罗和柞木的超微结构进行了研究。观察了这些木材的立体结构,导管壁上的纹孔,木纤维及其壁上的纹孔,纵向薄壁细胞及其壁上的纹孔,木射线薄壁细胞及其壁上的纹孔以及螺纹加厚和瘤层等,为教学、科研和阔叶木材的加工利用提供有意义的资料。 The ultrastructure of important broad-leaved tree ring boreal wood, Fraxinus chinensis, Ulmus pumila and Pinus elliottii in Northeast China was studied by means of scanning electron microscopy. The three-dimensional structure of these woods was observed. The pits on the conduit walls, the pits on the wood fibers and their walls, the longitudinal parenchyma cells and the pits on their walls, the palygorskite cells and the pits on the walls, Thread thickening and nodules, etc., for teaching, research and hardwood processing and utilization to provide meaningful information.
