title: Effect of cadaverine on Brassica juncea (L.) under multiple stress.
abstract: The cadaverine (Cad), an organic diamine was examined for its response on growth in salinity and metal stressed B. juncea cv RH-30 vis-à-vis compared the response of ammonium nitrate. The Cad (1 mM) application ameliorated the effect caused by salinity and metal stress on seed germination and plant growth. The plant growth recovery (dry biomass accumulation) was dependent on stress and diamine type. The higher growth recovery potential of Cad under both stresses was due to elevation in photosynthetic pigments, nitrate reductase activity and organic nitrogen as well as soluble protein, It is inferred that growth in stressed seedlings was mediated by Cad through lowering endogenous Cd/Pb and Na+ / K+ level in leaf and shoot tissues.
