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.
