摘要
茶树作为一种重要的经济作物,具有喜温、喜湿、喜阴的生态特性。然而,高温胁迫会影响茶树的生长发育,显著降低茶叶的产量和品质。文章综述了高温胁迫对茶树生理及重要次生代谢产物(儿茶素、茶氨酸、咖啡碱)影响的研究进展,并阐述了茶树响应高温的分子机制,以期为提高茶树栽培措施和选育耐热茶树品种提供理论依据。
Tea plant is an important cash crop and tea is widely popular in the world.However,tea plants prefer a warm and humid climate,and high temperature stress can seriously affect the growth and development of tea plants,significantly reducing the yield,quality and economic benefits of tea.This paper summarized the research progress on the effects of high temperature stress on the physiology and major secondary metabolites(catechins,theanine and caffeine)of tea plants,and described the molecular mechanism of tea plants in response to high temperature,with a view to providing a theoretical basis for the improvement of tea cultivation and the selection and breeding of heat-resistant tea cultivars.
