Fig. 4

Effect of application of melatonin (0, 75 and 150µM) on K+ (a), P (b), Ca2+ (c), Na+ (d) and Cl− (e) content of bitter melon roots 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 ≤ 0.05
