摘要: 茶叶香气是茶叶感官评价和品质化描述的重要组成部分。茶叶在采前自然生长与采后加工阶段参与多种胁迫响应,这些胁迫因子能够促进香气化合物的形成、积累与释放,积累的香气物质一方面有利于茶叶香气品质的提升;另一方面则有利于茶树逆境防御机制的产生。本文综述了近年来茶叶香气物质在胁迫响应方面的研究进展,如食叶害虫取食、病原菌侵染等生物胁迫和环境因子、加工工艺等非生物胁迫对茶叶香气物质代谢的调控机制以及茶叶香气响应胁迫在实际生产中的应用价值,为改善茶叶香气品质和茶树病虫害防御提供理论依据。

Abstract: Tea aroma is an important part in the sensory evaluation and commercial description of tea. During preharvest growth and postharvest processing, tea synthesizes, accumulates and releases aroma compounds in response to various stress factors. The accumulation of aroma compounds is beneficial to improve tea aroma quality and to develop the stress defense mechanism. This paper reviews recent progress in understanding the mechanism of the regulation of aroma compounds metabolism in tea in response to biological stress factors such as leaf-eating pests and pathogen infection, as well as abiotic stress factors such as environmental factors and processing and evaluates its application value in practice. We believe that this review provides a theoretical basis for improving tea aroma quality and preventing tea plant diseases and insect pests.

Key words: tea aroma; stress response; regulation mechanism; tea processing; pest and disease control
