摘  要:
本研究对不同杨树树叶、树皮、木质部的形态特征、组织结构进行了分析。毛白杨等白杨派树种叶片具毛,栅栏组组发达,树皮较光滑是黄斑星天牛不愿取食和刻槽产卵的重要机制;相反,大官杨、Ⅰ—214杨、加隆杨等黑杨派、青杨派及其杂种树叶无毛,海绵组织发达,树皮较粗糙,树皮和木质部质地较疏松,有利于天牛取食和刻槽产卵,因而成了黄斑星天牛的嗜食树种。

摘  要:
Describes the morphological characteristics of leaves, bark and wood of different strains of poplars in relation to sawyers damage. Plenty leaf hairs and palisade tissues with smooth waxy bark of Populus×tomentosa Carr. and other Leuce Duby are main causes that resistant to Anoplophora nobilis Ganglbauer to bore and oviposit. To the contrary, non-leaf hairs, rich in spongy tissues, rough bark and spongy cortex of P. ×euramericana cv. I-214, P. nigra L.cv. blane de garonne and other Aigeiros Duby and Tacamahaca Spach. and their hybrids are suitable for sawyers to bore and oviposit.
