Paper Title:
Concentration of Cadmium in Different Rice Cultivars
  Abstract

In order to study the variations among rice cultivars in cadmium (Cd) concentration abilities, pot soil experiments were conducted with six rice cultivars of different types at different soil Cd levels, i.e. 0.12 (the control), 5, 10 mg/kg. The results showed that there were great or obvious variations among the rice cultivars in Cd concentration abilities. But the magnitudes of the variations differed with soil Cd levels and plant organs. Generally, the magnitudes of the variations were larger for soil Cd treatment (5 and 10 mg/kg) than for the control. The magnitudes of the differences among the rice cultivars were higher in grains than in other plant organs. With regard to Cd concentrations in different organs of rice plant, they fell fast from root to grain. Bio-concentration factors (BCF) of Cd in rice plants were in the order: root > stem > leaf > grain. On the differences of soil Cd levels, BCF were in the order: the control > 5 mg/kg soil Cd treatment > 10 mg/kg soil Cd treatment.
