title: Changes in uptake of calcium caused by phytotoxicity of cadmium in Salvinia molesta.
abstract: : The effect of Ca on the uptake of Cd by root and leaves of Salvinia molesta was investigated at different time intervals and under different photoperiods. For detailed study on uptake and interaction, (15)Ca and (109)Cd were used and it was found that there was a higher uptake of (45)Ca in the root and leaves at 48 h and a concurrent reduction in (109)Cd content at 48 h suggesting alterations in Ca functions due to the phytotoxicity of Cd. Ultrastructural changes due to cadmium toxicity included swirling of thylakoid membranes of the chloroplasts as well as detachment of the tips of trichomes from the leaf.
