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.

Keywords: intercellular CO2 concentration; net photosynthetic rate; protein content; root length; stomatal conductance
Subjects: Bacopa monniera; cadmium, photosynthesis; CO2 concentration, intercellular, heavy metals; heavy metals, photosynthesis; in vitro culture, photosynthesis, heavy metals; net photosynthetic rate, heavy metals; photosynthetic rate, heavy metals; protein content, heavy metals; root growth, heavy metals; stomatal conductance, heavy metals; zinc, photosynthesis, heavy metals
