摘　　要：茶作为现今最为风靡的无酒精饮料之一,具有多种功效。但在铜的不同浓度胁迫下,会对茶树造成多方面影响。茶树中铜主要来源于土壤,其含量受多种外界因素影响,适量的铜离子利于茶幼苗生长,高浓度则抑制生长。铜在其他植物及茶树中迁移转化规律不同,且茶树根具较强富集性。铜对茶叶生化成分影响显著,缺铜降低品质,过量有害。不同植物对铜的抗氧化酶活性反应各异。在铜胁迫下,浓度高会破坏茶树超微结构,从而影响茶树的正常生长。本篇综述论文通过对茶树的生长发育、抗氧化酶的活性、生化成分的含量测定、超微结构的观察等方面结合铜的迁移转化规律,浅析铜在茶树中的迁移转化规律,为绿色茶叶的生产提供理论依据。As one of the most popular non-alcoholic beverages,tea has many effects.But under different concentration of copper stress,it will cause many effects on tea tree.Copper in tea plant mainly comes from soil,and its content is affected by many external factors.Proper amount of copper ion is beneficial to the growth of tea seedlings,while high concentration can inhibit the growth.The transfer and transformation of copper in other plants and tea tree were different,and tea tree root had strong enrichment.Copper has significant effect on the biochemical components of tea,lack of copper reduces the quality,excess is harmful.The antioxidase activity of copper in differ⁃ent plants varies.Under the stress of copper,the ultrastructure of tea tree will be destroyed and the normal growth of tea tree will be af⁃fected.Based on the growth and development of tea tree,the activity of antioxidant enzymes,the content determination of biochemical components,and the observation of ultrastructure,this paper analyzed the migration and transformation rule of copper in tea tree to pro⁃vide theoretical basis for the production of green tea.
