Changes in (A) the leaf phenotypes, (B) the maximum photochemical efficiency of PSII (F_v/F_m) and relative electrolyte leakage (REL) as influenced by melatonin or/and cold stress. Leaves of watermelon (Citrullus lanatus L.) seedlings at the four-leaf stage were pretreated with 150 μM melatonin (MT) for 3 days. Then, they were exposed to cold stress (i.e., 4°C) for 36 h. Data of F_v/F_m are the means of six replicates (±SD). Data of REL are the means of four replicates (±SD). Means denoted by the same letter did not significantly differ at P < 0.05 according to Tukey’s test. CK, Control; MT, Melatonin; Cold; MT-C, Melatonin+Cold.
