Research Abstract	Genotypic difference in Cd absorption and its associated with water uptake ability was examined. A marked genotypic difference was found in the grain Cd concentration under high Cd contaminated experimental field. The Cd absorption peaked during reproductive stage regardless of genptypes. The rhizosphere temperature affected the Cd absorption; the absorption was inhibited below 15℃. Water uptake ability did not correlated with the genotypic difference in the amount of Cd uptake in this study
