在电子显微镜下观察了王桉导管纹孔、射线薄壁细胞、纤维和管胞的碳复制品，显示了纹孔边界和纹孔封闭膜的详细结构。在所有的情况下，在成熟木材中，初生壁作为纹孔膜显然没有改变。与纤维管胞和管胞的纹孔边界不同，导管的纹孔边界不是分开的;边界的纤维素微纤丝可能是几个纹孔共有的。纤维纹孔边缘和管胞纹孔边缘发育为独立的实体，其结构类似于软木管胞纹孔边缘。与凹坑相关联的次级壁层的结构被描述并且与凹坑的结构相关。纹孔的精细结构特征，特别是纹孔封闭膜，讨论了液体进入木材的运动。
Observstion in the electron microscope of carbon replicas of the pits of vessels, ray parenchyma cells, fibres, and tracheids of Eucalyptus regnans has shown the detailed structure of the pit borders and the pit closing membranes. In all cases in the mature wood the primary wall is left apparently without modification as the pit membrane. Unlike the borders of the pits of fibre tracheids and tracheids, the pit borders of the vessels are not separate; the cellulose microfibrils of a border may be common to several pits. The pit borders of fibre traoheids and tracheids are developed as separate entities and have a structure similar to the pit borders of softwood tracheids. The structure of the secondary wall layers associated with the pits is described and related to the structure of the pits. The fine structural features of the pits, especially of the pit closing membranes, are discussed in relation to the movement of liquids into wood.
