摘　　要：茶树是我国南方地区的主要经济作物,近年来随着全球气候变暖的影响,茶树逆境胁迫日益严重,研究其生理特性和抗逆机制亟待加强。本文对近年来国内外有关茶树抗逆的生理表现及其抗逆途径进行综述,分析了干旱、高温低温、盐、低氮磷钾、重金属等逆境胁迫对茶树生长的危害,茶树可通过生长发育调节、渗透调节、代谢调节等诸多途径提高自身抗逆性。Global warming has brought about an ever-increasing stress seriously impacting the physiology and production of one of the major economic crops in China,Camellia sinensis.Consequently,research to further understand the stress responses and resistance mechanisms of tea plants has become urgently needed.This article reviews recently published domestic and foreign literature related to the plant physiology and methods for the resistance enhancement.The hazardous stresses of drought,waterlogging,high or low temperature exposure,salt,NPK deficiency,and heavy metal pollutants on the plant growth are discussed.Approaches based on the self-regulations on growth and development,osmosis,metabolism,and others by the plants to enhance the resistance to various stresses are presented.Relevant references on the plant physiology,tea quality and yield improvements,resource conservation,and development and utilization of tea cultivars are provided for in-depth studies.
