摘  要:
通过对不同程度为害的福云6号茶树品种鲜叶挥发物成分进行鉴定,发现经过跗线螨为害的茶树叶片鲜叶挥发物的种类增加,其中轻度危害鲜叶的挥发性气物质种类最多,共鉴定出66种;与正常鲜叶相比(未受为害叶片),不同程度为害叶片共新鉴定了46种新的挥发性物质;雪松醇、水杨酸甲酯、2-己基-1-辛醇、间-1,3,8-薄荷三烯等17种挥发物成分只在轻度为害叶片中检测出;香叶基香叶醇、D-柠檬烯、苯乙烯只在中度为害叶片中检测出;而可巴烯、柏木烯、雪松烯、氧化石竹烯、(+)-β-雪松烯、2-正戊基呋喃等10种物质仅出现于重度为害的茶树鲜叶样品中;3种不同程度茶跗线螨为害均诱导出己醛、α-紫罗酮、1,2,3,5-四甲基-苯、环十四烷、4-甲基-十五烷、十二烷等6种挥发性物质的产生。

摘  要:
The aromatic constituents in the fresh leaves of Fuyun 6tea(Camelliasinensis cv.Fuyun6)were found to increase significantly under varying degrees of Polyphagotarsonemus latus stress.There were 66 aromatic compounds in the leaves when the tea plants were under a medium stress.As the stress leve lincreased,46 new volatile substances were identified,as compared to control.17 aromatics,such ascedrol,methylsalicylate and 2-Hexyl-1-octanol,were detectedonly when the plants were subjected to a light stress.Some others,such as geranylgeraniol,D-limonene and styrene,existed only in the samples under a medium stress.A severe stress could cause the generation of 10 aromatics,such as copaene.All levels of stress tested in this study produced 6aromatic constituents including hexanal.
