| Abstract: | A hydroponic experiment and a pot experiment were conducted to investigate Cd uptake and translocation in rice and their physiological effects at several growth stages by using two rice cultivars with different grain Cd concentrations.In the pot experiment,the grain Cd contents of low Cd rice cultivar(A16) and high Cd cultivar(A54) were 0.31 mg/kg and 0.88 mg/kg,respectively at a total soil Cd concentration of 1.57 mg/kg.Both hydroponic and pot experiments showed that A16 absorbed and translocated more Cd t... |
