Relationship between cadmium absorption and water uptake ability in soybean with low cadmium absorption

研究了镉吸收的基因型差异及其与水分吸收能力的关系。在高镉污染试验田，籽粒Cd浓度存在显著的基因型差异。各基因型对Cd的吸收在生殖期达到高峰。根际温度影响Cd的吸收；在15℃以下，吸收被抑制。在本研究中，水分吸收能力与Cd吸收量的基因型差异无关

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
