Overview of Melatonin’s Impact on Postharvest Physiology and Quality of Fruits

Fruits are important horticultural commodities because they provide nutrients that help human health. mostly consumed as fresh products; however, there challenges in retaining the freshness, such rapid ripening process triggers fruit deterioration and reduces quality nutrient content. The postharvest of crops is affected by pre-and treatment. Most farmers use chemical compounds fungicides to prevent damage; this results health hazards environmental pollution. Melatonin can be used for maintaining improving fruits. a new bioactive compound potent free radical scavenger antioxidant. It has been studied an alternative harmful chemicals commercially management products. For health, melatonin plays regulatory role circadian seasonal rhythms, sleep, retinal functions, immune system. In plants, regulates many biological processes, particularly when plants have experienced abiotic stress, germination, aging, growth. effect exogenous on focused primarily relationship between ethylene plant hormones. Many studies recent years discussed melatonin’s delaying aging way increasing shelf life. This review provides comprehensive overview biosynthesis factors affect content fruit, mechanisms ripening, impact quality, change metabolite products,
