Abstract
The present investigation entitled "Studies on extending the shelf life of pomegranate (Punica granatum L. ) fruit Cv. Ganesh" with six postharvest treatments and two storage conditions was conducted in two sets of experiments with three replications in Factorial Completely Randomized Design. The treated fruits of pomegranate Cv. Ganesh were stored at room temperature (22.7 to 24.36'C; 52.0 to 82% R.H.) and in cool store (8*C; 90 to 95% R.H.), There was an increase followed by subsequent decrease in TSS, reducing sugars, total sugars and specific gravity with corresponding decrease in acidity and juice content upon prolonged storage of pomegranate fruits under both the storage conditions irrespective of postharvest treatments. Physiological loss in weight increased in storage in all the postharvest treatments and under both the storage conditions. Fruits stored in cool store followed the same trend of physico-chemical changes but at a slower rate. The shelf life of control fruit (untreated) was found to be hardly 15 days at room temperature. However, the fruit could be stored upto 30 days when it was coated with waxol + carbendazim (0.1%) at room temperature. The shelf life of untreated pomegranate fruit was 40 days and when coated with waxol, waxol + copper oxychloride, waxol + mancozeb, waxol + captan and waxol + carbendazim was extended upto 65, 65, 65, 70-and 75 days, respectively when stored in cool store.
