Effect of Different Post Harvest Treatments on Physical Characteristics of Custard Apple Fruits

摘要

The study was conducted with the objective to see the effect of different post harvest treatments on physical characteristics of custard apple fruits. Fruits were treated with different doses of gamma radiation ranging from 0.25 to 1.75 kGy in combination with antioxidant i.e. Benzyl Adenine (BA) @ 50 and 100 ppm and stored for 12 days at ambient temperature (25 +- 5 deg C, RH 90 +- 2%) during winter season. FrUits treated with low doses of gamma radiation i.e. upto 1.00 kGy along with 50 ppm benzyladenine extended the shelf life of fruits up to 6 days as compared to untreated fruits as well as fruits treated with higher doses of radiation. A decreasing trend in physiological weight loss (PLW) and percentage of marketable fruits was observed with increase in radiation doses. This promises to provide advantage to producers for transhipment of custard apple fruits in good and acceptable condition.
