The variations among six rice cultivars in cadmium (Cd) uptake and translocation were investigated with pot soil experiments. The results showed that only a very small portion (0.73%) of Cd absorbed by rice plant was transferred into grain. With regard to plant total Cd uptake, Cd concentrations and quantity accumulations in roots, stems and leaves, the differences among the cultivars (between the...
A pot soil experiment with 20 rice cultivars of different genotypes from different origins showed that the effects of lead (800 mg/kg Pb in soil) on rice growth and development varied greatly with different cultivars. The increases or decreases of the grain yields mainly resulted from the changes of the spikelets per panicle under soil lead treatment. Furthermore, the changes of spikelets per panicle...
