Salinity stress is the principal abiotic stress which has a decisive influence on plants by affecting germination, plant vigour and crop yield. The current study explores the protective role of non enzymatic antioxidants in scavenging ROS in Eruca sativa under salt induced oxidative stress. Hydroponically established seedlings of Eruca sativa var. DPY BKP 98 were subjected to NaCl stress at varying concentrations ranging from 10 mM to 150 mM. After 96 hours the treated plant were harvested to investigate the homeostasis and salt tolerance mechanism by analyzing the morphological parameters, stress and non enzymatic antioxidants. At 75 mM NaCl, the highest proline activity was recorded in leaves, shoots and roots which were 7.62, 2.58 and 1.28 folds respectively. The overall activity of other non enzymatic antioxidants (NPT) was also found to be 35.43% increase than control at this concentration. The highest activity of non antioxidants molecule imitated the decline in LPX and ROS at 75mM NaCl. The existing investigation demonstrated that Eruca sativa seedlings were tolerant towards salt stress and 75 mM NaCl facilitate the growth of the seedlings.
