Abstract

The present work was undertaken to study the effects of 24-epibrassinolide (24-EBL) on percent germination, growth (root length, shoot length, fresh weight and dry weight), lipid peroxidation, sodium and potassium ion concentrations, proline content, total osmolyte content, level of antioxidants (ascorbic acid, tocopherol and glutathione) in 7-day old seedlings of Raphanus sativus exposed to cadmium and mercury toxicity. Results of present study revealed that growth of seedlings was enhanced with the treatment of 24-EBL. In addition, 24-EBL was proved effective to overcome cadmium and mercury stress by altering the level of ions, osmoprotectants and antioxidants of plant.
