Effect of low temperature storage on chilling injury and storage life of commercial cultivars of mango (Mangifera indica l)

Abstract

An experiment was conducted to study the effect of low temperature storage on chilling injury and storage life of different commercial cultivars of mango (Mangifera indica L.) viz., Banganpalli, Dashehari, Peddarasam, Chinnarasam and Totapari stored at 8 oC ± 1 oC at Fruit Research Station, Sangareddy, Medak, Telangana. The experimental design is completely randomized design with factorial concept with four replications per treatment. Various physical parameters like Physiological loss in weight, fruit firmness, chilling injury and shelf life were estimated. Significantly lowest chilling injury was recorded in mango cv Totapari. The ripening was delayed when compared with that of varieties where the chilling injury was maximum. Maximum number of days (52 days) was recorded in mango cv Totapari for reaching the chilling injury score of 1.5. The chilling injury in mango cv Totapari and Peddarasm were observed from 25th day onwards while in other varieties it was observed from 15th day onwards.
