Exogenous melatonin improves seed germination in Limonium bicolor under salt stress.

ABSTRACT: Melatonin involves in improving tolerance to abiotic and biotic stresses by regulating various biological processes. However, little is known about the underlying mechanism. Here, we investigated the effects of exogenous melatonin on seed germination in the halophyte Limonium bicolor under salt stress. Specifically, we examined the effect of salt stress on seed germination, melatonin concentration, and changes in the concentrations of nutrients, amylase activity, and hormones in L. bicolor seeds with and without pre-treatment with melatonin. Seed germination was significantly suppressed under a 200 mM NaCl treatment, but pre-treatment with melatonin significantly improved seed germination under salt stress. During seed germination, seeds pre-treated with melatonin contained h
