The discussion includes the more familiar physical and chemical changes which occur during the period of fruit maturity and ripening, together with the results secured in the ripening of fruit by the use of ethylene gas. Fruits undergo ripening process either during pre-harvesting period on plants or during post-harvesting time. The cause of fruit ripening is a natural form of a chemical synthesized to make PVC (polyvinyl chloride) piping and plastic bags—namely, a gaseous plant hormone called ethylene. This process involves a series of changes in the composition of the fruit, including the conversion of starch to sugar, that are triggered by a cascade of chemical and biochemical reactions in the fruit. Moreover, authors have investigated sucrose metabolism in climacteric fruits during ripening such as banana and mango but studies of sucrose metabolism during growth and development of climacteric fruit such as mango has been rarely explored.
