Abstract
This study evaluates the impact of cadmium and zinc interaction on the amount of soluble proteins, CO2 fixati stomatal conductance and intercellular CO2 contents in regenerants of B. monniera. The regenerants were grown 16 weeks on MS medium containing cadmium and zinc in various concentrations. Cadmium decreased the stom conductance, photosynthetic rate and root growth but increased the protein content. Additional supply of zinc in medium reduced the adverse effects of cadmium on these parameters.
