茶角胸叶甲适度侵害对岭头单枞茶鲜叶内含成分的影响

The effect on the component contents in fresh leaves of Lingtou Dancong tea plant by moderate damage of Basilepta melanopus

摘要: 在同一块茶园中，在不控制茶角胸叶甲侵害的情况下，经过一段时间侵害后，根据茶角胸叶甲侵害茶树程度的不同，探讨茶角胸叶甲不同程度侵害对单枞茶新梢内含成分的影响．试验结果表明：茶角胸叶甲侵害能明显降低茶多酚、氨基酸含量，增加黄酮类含量；中度侵害能显著提高儿茶素含量，轻度侵害能明显提高可溶性糖含量，重度侵害则明显降低可溶性糖含量．茶角胸叶甲适度的侵害能改变鲜叶内含物的含量，对提高茶叶品质有利．

Abstract: The effect of the different damage types of Basilepta melanopus Lefevre was researched on the component contents in fresh leaves of Lingtou Dancong tea plant.The results showed that Basilepta melanopus Lefevre's damage could evidently decrease the content of polyphenols and amino acid,while increase flavonoide content,its light damage could obviously increase soluble sugar content,middle damage could significantly increase catechin content,while severe damage could obviously reduce soluble sugar content.Its damage could change the component content in fresh leaves which benefited to improving the quality of Lingtou Dancong tea.
