| 摘 要： | 对５０种主要造林阔叶树种形态特征，组织解剖结构进行观察，结合对光肩星天牛，黄珏星对天牛危害调查进行了分析，得出树皮的粗糙程度与天牛的选择刻槽产卵有关，与树皮颜色无在。皮层和韧皮部中的石细胞，结晶体的分布，数量，纤维素的多少，排列状况，木栓层厚度，组成，后含物均能影响树木的抗虫性能。

| Abstract: | Through the observation on the morphological characteristics and dissection structures of 50 species of broadleafs and the analysis of the harmfulness caused by Anoplophora nobilis and A.glabripennis, it is concluded that the impressing ovipositon is related to the roughness of bark instead of colour.The insect resistance of a tree is influenced by several factors,such as the distribution and quantity of stone cell and crystals in cortex and phloem,the content of cellulose,the thickness and composition of cork layer, etc. |
