摘要: 详细介绍了长白鱼鳞云杉、臭冷杉木材的显微和超微构造特征及其对木材渗透性影响,两树种的心材管胞具缘纹孔膜和管胞胞壁各层纤丝中丰富的无定形物质的沉积是心材渗透性差的解剖方面的主要原因。

Abstract: This paper gives a detailed description of microscopic and ultrastructure and their effects on the permeability of the woods of Picea jezoensis var. komarovii and Abies nephrolepis. The abundent amorphous substances are depo-sited in the bordered pit membrances and the different layers of cell wall andaround the microfibrils of tracheids, that may be a main factor of the lowpermeability in heartwood of the two woods.
