Effect of selenite and selenate on plant uptake of cadmium by kidney bean(Phaseolus mungo)with reference to Cd—Se interaction

Abstract

Pot culture experiments have been conducted to study the effect of selenite and selenate pretreatment on the uptake and translocation of root-absorbed cadmium in the kidney bean plant, irrigated with 2 μg mL−1 of Cd. A statistically significant reduction in cadmium uptake with increasing concentration of selenite and selenate (0.5–6.0 μg mL−1) has been observed. Selenite treatment is found to be more effective in decreasing cadmium uptake.
