摘要
该文通过对９ 种树种组织解剖结构特征的观测，运用逐步回归方法，分析了树种解剖特征的差异与天牛危害之间的关系．结果表明，不同树种在同一立地条件下的导管个数、射线宽度、木化细胞半径及韧皮部石细胞壁的厚度与树种的抗虫性密切相关；同一树种在不同立地条件下其内部解剖结构有所不同．
Based on intensive observation and measurement to the characteristics of tissue anatomical structure of some tree species, the relation of anatomical structure of tree species and their resistance to longicorn beetles was studied systematically with stepwise regression analysis. The result shows that the resistance of tree species at the same site closely related to the number of vessel, rays' width, radium of lignified cell and wall thickness of sclereids, and the anatomical structure of the same tree species was different at different sites.
