摘要:

本研究简述了镉、铬、砷、钒、铜5种重金属元素污染对枸杞和其他作物生长及品质影响。归纳了枸杞植株应对镉、铬、砷等5种重金属胁迫的机制,以及在亚细胞层面枸杞解毒重金属胁迫的研究进展。提出了现阶段枸杞响应重金属胁迫相关研究存在的问题和未来研究方向,如土壤重金属含量与枸杞根、茎、枝条、叶片、果实中重金属含量间的迁移转化、枸杞植株的重金属胁迫响应机制、分子机理等,以期为枸杞清洁化栽培的应用和改进提供参考。

Abstract:

This study briefly describes the impact of pollution by five heavy metal elements, namely cadmium, chromium, arsenic, vanadium, and copper, on the growth and quality of Lycium barbarum and other crops. It summarizes the mechanisms of L. barbarum to cope with the stress of cadmium, chromium, arsenic, and other five heavy metals, as well as the research progress on detoxification of heavy metal stress at the subcellular level in L. barbarum. The study points out the existing problems in current research on L. barbarum response to heavy metal stress and future research directions, such as the migration and transformation of heavy metal content between soil and various parts of the L. barbarum, including roots, stems, branches, leaves, and fruits, the response mechanisms of L. barbarum to heavy metal stress, and molecular mechanisms, in order to provide references for the application and improvement of clean cultivation of L. barbarum.

Key words: Lycium barbarum, heavy metal, stress, soil, response mechanism
