%X 茶树具有聚氟特性，是植物界氟含量最高的几种植物之一。本文主要从茶树富氟特点和分布规律、茶树氟生理等方面进行综述，并提出了茶树耐氟的5种可能机制，即茶树对氟的吸收模式与有效转移、茶树次生代谢对降低氟毒害的作用、茶树保护性酶和非酶抗氧化剂对氟毒害的防御、茶树体内氟化物的存在形式对氟毒害的缓解、茶树细胞壁对氟的固定与解毒作用。<br>Tea plant which has strong ability to accumulate fluoride is one of the several plants containing richest fluoride.In this paper,the absorption and distribution of fluoride in tea tree and the influences of fluoride on physiology of tea plant was reviewed.The possible mechanisms including the uptake and transfer way of fluoride for fluoride-resistant,the role of secondary metabolites in reducing poison of fluoride,the defense system against the free radical injury under fluoride stress,the toxic effect of the combined forms on fluoride and the detoxification of cell walls in fixation of fluorine were discussed.
