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

研究了镉吸收的基因型差异及其与吸水能力的相关性。高Cd污染试验田籽粒Cd浓度存在显着的基因型差异。无论基因型如何，镉吸收在生殖阶段达到峰值。根际温度影响Cd吸收； 15℃以下吸收受到抑制。本研究中吸水能力与 Cd 吸收量的基因型差异不相关
