水稻铅污染研究进展(综述)

Research Progress on Lead Pollution in Rice

铅是一种对水稻(Oryzasativa L.)生长发育毒性显著的污染物质,农田土壤中铅的存在形式和含量直接影响稻米的产量与品质。本文从土壤中铅的存在形式、水稻对铅的吸收富集规律、铅污染对水稻生长发育的影响、水稻对铅污染的生理生化效应以及抗性机制等方面进行系统地分析论述。

The lead is a kind of severely-toxic polluting stuff to rice＇s growth and development, since the output and the quality of rice are both affected by the lead＇s content and existing form in the farmland soil. Five aspects are analyzed and summarized systematically in this paper such as the lead＇s existing form in soil, the absorption and enrichment rule of lead in rice, the effect of lead＇s pollution on the rice＇s growth and the physiological biochemical effect of rice under lead pollution, and rice＇s resistant mechanism toward lead pollution.
