Today different stresses arise due to climate change, as well as due to natural and man made activities. Melatonin, once discovered in vertebrates as a hormone of the pineal gland, is now known to be formed in bacteria and numerous taxa of eukaryotes including various algae of different phylogenetic position and plants.

Thus their application in these crops has been extended to alter a variety of responses. Some plant species or cultivars are responsive to specific PGRs, but not all PGRs. Hormone can be defined as a substance produced in one part of the organism...
