Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were
determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a
decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more
detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd ( μM) to
and by Pb ( μM) at the flowering stage. Proline showed increase at lower
concentrations of Cd and Pb but at higher concentrations it showed decrease. More accumulation of
Cd and Pb was observed in roots than shoots in B. juncea. Cd was found to be more accumulated than
Pb but higher concentrations of Pb hampers the Cd absorption.
