摘要: 通过不同程度的茶角胸叶甲虫侵害胁迫处理,研究了广东主栽岭头单枞茶鲜叶香气物质的变化.结果表明,茶角胸叶甲侵害的处理能明显地提高鲜叶芳香物质的种类,其中中度侵害处理的香气种类最多,共有36种;随着侵害处理程度的加深,1,6-亚甲基轮烯等9种物质含量增加,而芳樟醇等8种物质含量则下降;2-甲基十六醇等4种物质只在轻度侵害处理中出现,而二十二碳-1-醇等6种物质只在中度侵害处理中出现;不同程度的侵害胁迫,能诱导形成不同种类的芳香物质的合成,侵害处理可诱导1,6-亚甲基轮烯等23种物质的形成,同时也可抑制壬醛等6种物质的形成.

Abstract: The study showed that under different degrees of Basilepta melanopus Lefevre stress, the kinds of aromatic constituents in the fresh leaves of Lingtou Dancong tea plant increased evidently, being the most (36 kinds) under medium stress. With the increase of the stress, the contents of 9 aromatic constituents like 1,6-methylene annulene increased, whereas those of 8 constituents as linalool decreased. Light stress induced the appearance of 4 aromatic constituents like 2-methyl hexadecane, while medium stress induced that of 6 constituents as H1-docosanol. Different degrees of B. melanopus stress could induce the synthesis of 23 aromatic constituents like 1,6-methylene annulene, but inhibit the formation of 6 constituents as nonanal.
