十二种落叶栎木的木材分类

CLASSIFICATION OF TWELVE OAK SPECIES BY MEANS OF WOOD STRUCTURE

本文研究了12种落叶栎木的解剖构造,按其主要特征,编制出识别木材的检索表。并运用木材定量解剖的方法,测定晚材管孔在纲格上的点分数、单位面积上的管孔数、密度指数以及它们之间的间距,将12种落叶栎木分为四组及二个单独的种。短柄枹栎和枹栎的木材解剖构造和定量解剖分析上都有显著地差异,可以将短柄枹栎单列为一种;麻栎和栓皮栎在形态分类上比较接近,而木材构造和定量解剖分析差别较大,栓皮栎可作为单独一个种,不包括在麻栎组内。

Anatomical structures of twelve oak were studied. A dichotomous key is proposed according to their main features and some quantitative studies by means of point counting of anatomical wood features in the grid areas were also attempted. Quercus glandulifera var brevipetiolata Nakai. and Q. glandulifera Bluma. are obviously different in wood structures. The outer appearance of Quercus acutissima Carruth. and Q. variabilis Blume. trees are quite alike but they are different enormously in wood anatomical structures. So, these twelve oak species could be classified into four groups with two additional seperate species.
