摘要
茶树是我国重要的经济作物,对锗元素具有较强的吸收利用能力,从而促进自身生长发育。经过生物富集作用,茶树将有毒的无机锗(GeO_(2))转化为无毒的有机锗(Ge-132),其中有机锗极易为人体所吸收,有益于身体健康。目前锗在茶树中的应用研究尚处于起步阶段,深入探究其富锗机制是研究开发富锗茶的关键。因此,综述了土壤中锗的分布及其与茶树生长的关系、茶树对锗的吸收利用以及锗在茶树中的富集作用及机制,为今后提高茶树对土壤锗的吸收效率及富锗茶的种植开发提供基础信息和理论参考。
Camellia sinensis is an economically significant crop in China,which can absorb and utilize germanium,thus promoting its growth and development.Through bioenrichment,Camellia sinensis transforms toxic inorganic germanium(GeO_(2))into non⁃toxic organic germanium(Ge⁃132).Moreover,the organic germanium can be absorbed by human and is beneficial to health.The application research of germanium in Camellia sinensis is still in the initial stage,and it is important to explore the germanium accumulation mechanism for developping germanium⁃rich tea.Therefore,the distribution of germanium in soil,the relationship between germanium in soil and growth of Camellia sinensis,the absorption and utilization of germanium by Camellia sinensis and the accumulation mechanism of germanium in Camellia sinensis were reviewed,which will provide basic information and theoretical reference for improving the germanium absorption efficiency of Camellia sinensis from soils and planting germanium⁃rich tea in the future.
