Interaction of selenium and cadmium in wheat at different salinities

AbstractInteraction of Se up to 8 mg kg−1 soil and Cd at 5 and 15 mg kg−1 soil in wheat at different salinities was evaluated. Se concentrations in wheat shoots were progressively increased in parallel to Se in soil but decreased by addition of Cd. With increasing salinity, Cd concentrations increased and Se decreased. At low salinity, low addition of Se to the soil reduced Cd accumulation. At moderate and high salinities, only high Se amendment led to decline in Cd uptake, at the expense of reduction in biomass yield. Se at 0.5 mg kg−1 soil alleviated the negative effect of Cd on shoot yield.
