对云斑白条天牛具有不同抗性的杨树品种中挥发物成分的研究

Study on Volatile Constituents of Populus deltoides with Different Resistant Ability to Batocera horsfieldi

摘要: 研究了对云斑白条天牛有不同抗性的杨树品种中挥发物的化学成分,通过GCMSDS分析,鉴定了68个成分,南抗1号A3417杨中挥发物成分最多,271杨最少,Ⅰ69杨与297杨居中。研究发现不同抗性的杨树的烷烃含量及提取物含有的挥发物成分的数量与抗性一致。另外,南抗1号A3417杨、297杨和Ⅰ69杨中松柏醇的含量远远高于271杨,具有高抗性能的南抗1号A3417杨中有机酸、醛、酮、酯等成分明显高于其他品种。

Abstract: The volatile constituents resistant to Batocera horsfieldi in 4 kinds of Populus deltoides were studied. Sixty eight constituents were determined by GC MS DS. It is discovered that the better the resistant ability to B.horsfieldi, the higher the content of alkyl hydrocarbon in the 4 varieties of P. deltoides tested. Twenty four main constituents were clustered. The result of clustering analysis coincides with the actual situation.
