In a trial conducted at Navsari Agricultural University, Navsari putrescine was applied at three different levels (1, 2 and 3mM) to mango cv. Kesar, as preharvest spray (10 days before harvesting), postharvest dip (5-6 min) and preharvest spray + postharvest dip treatment. Methods of application and levels of putrescine had a significant impact on all parameters included in the study except pulp: peel ratio. Preharvest spray +postharvest dip of putrescine @ 2mM emerged as the best treatment combination for mango fruits exposed to this treatment could be stored for 20 days at 11±1°C & 90-95% RH. Fruits thus treated had the lowest spoilage, maximum firmness and the highest organoleptic scores. These results throw light on the potential use of putrescine in prolonging the shelf life of mango without any detrimental effect on fruit quality. This technology can be put to use when transporting fruits to high end and distant markets
