Abstract

In this study, we have evaluated the co-application of epibrassinolide (24-EBL) and putrescine (Put) on stress indicators and antioxidant system of Solanum lycopersicum L. grown under salinity stress. EBL and Put application along with NaCl stress showed differential responses in the activities of antioxidant enzymes (superoxide dismutase, catalase and guaiacol peroxidase). Significant increase in lipid peroxidation was observed in tomato plants treated with NaCl stress. A remarkable decrease in lipid peroxidation (LPO) was observed in plants treated with 24-EBL and Put supplemented with salt stress. Application of 24-EBL and Put was able to restore the ill effects on photosynthetic pigments (PPs). Moreover enhanced titers of ascorbic acid (ASA), total phenols (TPC), glutathione (GSH), proline and glycinebetains (GB) were also observed in tomato plants supplemented with 24-EBL and Put with/or without NaCl stress.
