Shoots and roots of Bacopa monniera (L.) Wettst. have been regenerated from nodal segments on MS medium containing combinations of NAA and BAP. The cultures showed 100% regeneration on MS (sucrose 2%) medium added with NAA(0.2 mg L-1), BAP (0.5mg L-1) and glutamine (50 mg L-1). Supplemented with aluminium chloride (up to 400 $mu$M), this medium could ensure successful survival of regenerants. All the regenerants, maintained on AlCl3-supplemented medium for the last three years, failed to grow when transferred to AlCl3-free media. Aluminium stress also induced synthesis of proline and proteins. The rate of photosynthesis decreased at increased aluminium concentrations.
