摘要
采用SDE法,分离提取了假眼小绿叶蝉取食诱导和正常茶梢挥发物,并应用气质联用仪(GC-MS)进行分析和比较,探讨假眼小绿叶蝉取食诱导茶树间接抗性的机制。结果表明,假眼小绿叶蝉的危害诱导反式-β-罗勒烯、正辛醇、芳樟醇、(E)-β-法尼烯、水杨酸甲酯、苯甲醛和吲哚等对天敌具有引诱活性的互利素含量上升。
Tea shoots volatiles were collected using a simultaneous distillation and solvent extraction（SDE）.The volatiles emitted from tea green leafhopper-infested plants（infested for 24h）and intact plants were collected：The volatiles were analyzed with a GC-MS.We examined the difference of tea shoots volatiles from intact and infested by tea green leafhoppers.The mechanism of indirect resistance of tea plant infested by tea green leafhoppers was discussed.Tea green leafhopper infestation significantly enhanced the release of volatile synomone,i.e.（E）-3,7-Dimethyl-1,3,6-octatriene,Octanol,1,6-Octadien-3-ol,3,7-dimethyl,alpha Farnesene,Methyl salicylate,Benaldehyde,Indole and so on.
