引言 东北针叶树材的粗视构造及显微构造研究较多,并有专著出版,但对于东北针叶树材的超微构造观察尚为罕见。为了透彻了解东北针叶树材的特性及其与木材性质、木材加工的关系,利用透射电镜进行观察,现将紫杉、樟子松、油松、鱼鳞松、红皮云杉、奥松和杉松木材的超微构造进行报导。根据观察结果,主要介绍管胞和管胞毗邻的 Introduction The research on the macrostructure and the microstructure of the northeastern coniferous woods is more and more published in monographs. However, it is rare to observe the ultrastructure of the coniferous woods in Northeast China. In order to fully understand the characteristics of northeast coniferous wood and its relationship with the properties of wood and wood processing, using transmission electron microscopy to observe, now yew, Pinus sylvestris, Pinus tabulaeformis, spruce, spruce, Aosong and fir The ultrastructure of wood is reported. According to the observations, mainly introduced tracheid and tracheid adjacent
