| Title : | EFFECT OF GLYCINEBETAINE ON GROWTH AND ANTIOXIDANT ENZYMES OF SAFFLOWER UNDER SALINITY STRESS CONDITION |
| Abstract : | In the current study, the effect of glycinebetaine (GlyBet) on some vegetative and physiological characteristics of safflower under salinity stress conditions. Salinity (0 (non-stress), 50, 100, and 150 mM sodium chloride (NaCl)) was applied via the nutrient solution, and GlyBet (0, 10, 30, and 60 mM) was applied as foliar spray to safflower plant's leaves. The results showed that salinity reduced growth traits, relative water content (RWC), and peroxidase (POD) activity and increased malondialdehyde (MDA), proline, total soluble sugars, catalase (CAT), and superoxide dismutase (SOD) activity. Glycinebetaine at 60 mM increased root length, shoot length and RWC content compared to the control (0 mM GlyBet) under all salinity levels. Foliar spraying of salt-stressed plants with 30 and 60 mM GlyBet increased root and shoot dry weight, total soluble sugars and proline contents compared to the control. Foliar application of GlyBet induced activity of CAT and inhibited POD and MDA contents under all stress levels whereas it had no effect on SOD activity |
