Influence of post-harvest application of GA and Ca on shelf-life of banana (Musa spp.) cv. grand naine

The present study was undertaken at Post Harvest Laboratory, Department of fruit Science and Horticulture Technology, OUAT, BBSR during 2015-16 and 2016-17 to envisage the effect of different post harvest treatments in shelf-life of banana cv. Grand Naine where fruits were subjected to ten treatments with different concentration of GA3, CaCl2, their combination and Control (without any treatment) and replicated thrice. Fruits were treated in different concentration of chemicals/growth regulator delayed pulp to peel ratio, Physiological loss in weight, decay % and shelf life as compared to openly kept control banana. But, fruits treated with GA3 @150ppm (Dipping) recorded significantly lowest PLW (10.72% in plant crop and 10.77% in ratoon crop), pulp: peel (2.48 in plant crop and 2.46 in ratoon crop), decay % 55.02 in plant crop and 55.27 in ratoon crop) in longest storage observation (on day 21st day) with a maximum shelf life up to 22.04 days in plant crop and 22.07 days in ratoon crop compared to 12.27 days in plant crop and 12.32 days in ratoon crop only for untreated fruits.
