In order to understand the mechanisms on the variation between rice cultivars in Cd up.ake and accumulation, two p.t soil exp.riments were conducted with typ.cal rice cultivars that varied greatly in soil Cd up.ake. The exp.riments with six rice cultivars showed that the root oxidation abilities of rice differed with rice cultivars and also with typ.s of the cultivars, the cultivars with indica consanguinity were significantly higher than the cultivars with jap.nica consanguinity. Root oxidation abilities of the rice cultivars correlated p.sitively and significantly （p.0.01） with their Cd concentrations and Cd quantity accumulations in rice p.ants. The exp.riments with two rice cultivars showed that significant differences also existed between the two cultivars in p.t soil redox p.tentials, which of Shan you 63 （higher soil Cd accumulator） were significantly higher than that of Wu yun jing 7 （lower soil Cd accumulator） under different soil Cd levels, but the degrees of the differences varied with soil Cd levels. The differences were larger under soil Cd treatments than the control. The results indicate that root oxidation ability, esp.cially in Cd contaminated soil, is one of the main mechanisms which dominate Cd up.ake and accumulation by rice p.ant.
