Fig. 1From: Exogenous melatonin increases salt tolerance in bitter melon by regulating ionic balance, antioxidant system and secondary metabolism-related genesEffect of application of melatonin (0, 75 and 150µM) on Proline (a) and RWC (b) in bitter melon under salt stress (0, 50 and 100 mM NaCl) conditions. Data are the average of 3 replicas ± standard error. Different letters show significant difference according to Duncan’s multiple range test at p ≤ 0.05Back to article page
