Abstract: The gaseous plant hormone ethylene plays a key regulatory role in fruit ripening and also know as ripening hormone. Autocatalytic production of ethylene causes detrimental effects by increasing rate of respiration, accelerate senescence and chemical changes which affect post-harvest life and quality of fruits. Various tools are used for management of ethylene during post-harvest stage are control atmospheric storage, modified atmospheric storage but it has its own limitations and most of the time leads to disorders like superficial scald, melting flesh, chilling injury etc. The 1-MCP is competitive inhibitor of ethylene action which maintain fruit quality by delaying senescence. It is a gaseous chemical that can be easily applied, non-toxic mode of action and activity at very low concentration increases its commercial importance. The 1-MCP is registered by more 37 countries for use in various fruits after approval by Environmental Protection Agency from USA. A treated fruit have lowered ethylene production, slow rate of respiration and maintained physiochemical properties during both ambient and cold storage. Various genotypes, cultivars and maturity stages at time of treatment give varying response to the 1-MCP. It has effects on different physiological disorders; the proneness of fruits to various disorders can be increased or decreased by inhibition of ethylene production. The Nitric oxide (NO) known to act as a biological messenger and plays important role in Inhibition of ethylene biosynthesis and its related detrimental effect on fruits during post-harvest storage. The production of ethylene in fruits were reduced by the use of Nitric oxide as ACC oxidase–Nitric oxide complex is formed after the treatment of Nitric Oxide. It is concluded from review, that NO & 1-MCP are multifunctional signalling molecules plays significant role in postharvest physiology of fruits by reducing ethylene biosynthesis and rate of respiration.
