中文摘要：

干旱是影响茶叶生产的主要气象灾害之一。茶树对干旱胁迫及随后复水的响应非常复杂，探究茶树耐旱机理，对于发掘利用耐旱节水基因资源、提高耐旱性和水分利用效率、发展节水抗旱栽培、减轻旱灾损失具有重要意义。本文简述了干旱对茶树生长发育、产量和品质的影响，述评了当前茶树响应干旱胁迫和复水机理的研究动态，概述了茶树节水抗旱栽培和灾后恢复技术，并展望了今后研究重点。

英文摘要：

Drought is one of the pivotal meteorological disasters affecting tea production. Responses of tea plant to drought and rehydration are very complex, so it is vital to study drought-resistance mechanism for exploring relative genetic resources, improving water use efficiency and drought resistance, developing water-saving and drought-resistance cultivation and subsequent reducing losses. Here, effects of drought stress on growth, development, production and quality of tea were presented. We try to provide a brief insight into how tea plant responds to drought and rehydration. Some recent studies on strategies for water-saving and drought-resistance cultivation and subsequent recovery had been reviewed, and major research trends were discussed.
