镉对水稻的毒害效应及其调控措施研究进展

Review of Toxic Effect of Cadmium on Oryza Sativa and Remediations

镉是植物生长的非必需元素,它易于被吸收,具有很大的生物毒性。镉通过在水稻内富集而进入食物链,对人畜健康构成巨大威胁。在参阅大量文献资料的基础上,概述了土壤中镉对水稻的毒害效应及水稻对镉的吸收分配作用,讨论了目前降低其毒性的调控措施。

Cadmium,as one of unnecessary elements for plant growth,is toxic and easier to absorb and it can accumulate in rice to harm human and animal health through the food chain.Based on literatures,the poisonous effect of cadmium on Oryza sativa were summarized,absorption,distribution,translocation and accumulation of cadmium in rice plants were reviewed,the remediations to alleviate the poisonous effect presently were discussed.
