In order to pursue higher yield of rice, higher amount of NO 3− is often used in rice
production, but limited information is available on cadmium (Cd) uptake promoted by nitrate
(NO 3−) in rice. Here, hydroponic experiments with integration of three NO 3− levels (0 mM,
2.86 mM and 5.72 mM simplify as 0, NO 3− and 2NO 3−) and two Cd concentrations (0 and
100 μM) were conducted. Phenotypes and physiological indexes related to Cd uptake were
measured; content changes of nitrogen, Cd and Fe also were measured. In addition, net Cd …
