[Objective] The present paper aimed to explore the effects of Cd stress on the absorption and transport of mineral elements in rice.[Method] 29 rice varieties were selected and treated with two groups (0,0.5 mg/kg). The contents of eight mineral elements (Ca, Fe, Zn, Mg, Cu, Mn, K,Na) in the upper and lower parts of rice were measured by atomic absorption flame spectrophotometer.[Result] In the underground part, compared with control group, the effect of Cd on Fe was shown to inhibit absorption; Zn, Mg, K and Na were resistant to Cd, and Zn was more resistant than Cu, and Cd was more competitive than Mn and Mg.Its Cd resistance and competitiveness were greater than that of Ca. Zhuzhen B and Japonica 7623 showed Cd tolerance among the eight mineral elements. [Conclusion] Zhuzhen B was the only rice variety that promoted the absorption of eight mineral elements after Cd stress; Liusha 1 was the least Cd-tolerant rice variety. [ABSTRACT FROM AUTHOR]

Field investigation and the mathematical statistic method were conducted to investigate the effect of environmental factors on the cadmium uptake of heavy metals in rice. The results showed that there was a negative correlation between Cd and soil pH, Mn, Fe, Zn, Mg, Mn, and among them the soil pH were significantly negative correlated with Cd (- 0. 672) ; whereas the correlation coefficient between Cd, the soil organic matter, available Cd, and total Cd were positively correlated, in which the soil organic matter and available Cd were significantly positive correlated with Cd. The correlation coefficients were 0. 579 and 0. 631 , respectively. [ABSTRACT FROM AUTHOR]
