Abstract
|
|
|
|
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㎎ L^-1), BAP (0.5㎎ L^-1) and glutamine (50㎎ L^-1). Supplemented with aluminium chloride (up to 400μM), this medium could ensure successful survival of regenerants. All the regenerants, maintained on AlCl_3,-supplemented medium for the last three years, failed to grow when transferred to AlCl_3-free media. Aluminium stress also induced synthesis of proline and proteins. The rate of photosynthesis decreased at increased aluminium concentrations.
