The present work aims at protracting the lifespan of plums cv. Gulfblaze, originating from Holambra II, São Paulo, by application of gamma irradiation and packaging on cold fruits. The experiment were made: 0,0; 0,4; 0,6; 0,8; 1,0KGy undergo a passive modified atmosphere. The fruits were selected and packed, and then irradiated at IPEN, located in São Paulo - SP. Thereupon, they were directed to the Laboratory of Fruit and Vegetables from the Department of Management and Agribusiness Technology of the Agronomic Sciences Faculty ­- UNESP -­ Botucatu, Brazil. In this experiment, after the treatment the fruits were stored in B.O.D at 0±2°C with 90±5% RH for 35 days. Evaluations were conducted every five days, for the 35 days of storage. Alterations on post-­harvest quality were detected by means of analysis of fresh mass loss, consistency (firmness), reducing sugar content, total reducing sugar, vitamin C total, phenolic compounds and respiratory rates. The employed statistical design was thoroughly randomized with three replications per treatment for each of the eight evaluations using the Turkey's Test to 5% of probability. Under the circumstances in which the experiments were performed, the results allow for the conclusion that the use of gamma radiation did not lead to improvement, regardless of the applied dose.
