不同基因型水稻镉吸收差异及镉对水稻的影响研究进展

Research Progress of Cadmium Absorption of Different Genotypes of Rice and the Effect of Cadmium on Rice

研究镉对水稻污染的生理生物学的作用机制,筛选富镉或低吸镉的水稻基因型品种对保护生态环境和生产绿色食品都具有重要的理论意义和实用价值。综述了稻田镉污染的现状、危害,水稻镉吸收积累差异以及镉对水稻生长发育的影响等方面的研究成果,并提出了今后的研究方向。

Cadmium and other heavy metals is the world′s major environmental problems,pollution of cadmium on rice physiological mechanisms of biology,screening rich cadmium or cadmium in rice genotypes bargain-hunting is extremely important to protect the ecological environment and its green food production have important theoretical significance and practical value. This article on the status of paddy cadmium pollution,harm,rice,and the difference of cadmium uptake and accumulation of cadmium on rice growth and development of other aspects of the study were reviewed.
