摘　　要：运用高效液相色谱法(HPLC)测定7种不同品系杨树韧皮部中6种酚酸的含量,并观察外源施用酚酸对青杨脊虎天牛的驱避作用。结果表明,每种酚酸的含量在不同品系杨树中差异显著水平不同,被测定的6种酚酸含量之间均呈正相关关系,部分酚酸含量之间相关性达显著水平;6种酚酸对青杨脊虎天牛均有不同程度的驱避作用,其中以咖啡酸、肉桂酸、丁香酸效果更为明显,驱避率在78%以上。The research has been done by using HPLC in order to measure the content of six kinds phenolic acids in seven strains of poplars＇ phloem, and observe the resistance to the Xylotrechus rusticus Linnaeus by applying to exogenous phenolic acids. There is significant different level of content of each phenolic acid in different strains of poplar. The content of the six phenolic acids measured had positive correlation with each other, some of which reached a significant level. The six exogenous phenolic acids have effect on the resistance of Xylotrechus rusticus to different extents, especially in caffeic acid, cinnamic acid and syringic acid, the rate of resistance in which is more than 78%.
