Abstract:
The present study was undertaken at Horticulture Research Station, Department of Fruit Science and Horticulture Technology, College of Agriculture, OUAT, BBSR during 2015-16 and 2016-17 to envisage “Pre harvest application of GA3 and CaCl2 on physiological loss in weight (PLW) % and storage life of banana cv. Grand Naine”. In this experiment fruits were subjected to ten treatments with different concentration of GA3, CaCl2, their combination, control (with water) and replicated thrice, after male bud removal chemicals were applied to the bunch by spraying. In this experiment maximum physiological loss in weight 13.73% (2015-16), 14.16% (2016-17) was recorded in control on 12th day of storage, where as on 12th day in GA3 @150 ppm it was 7.25% (2015-16), 6.19% (2016-17) and attains its maximum value on 18th day. Fruits treated with GA3 @150 ppm had dramatically more delayed physiological weight loss, pulp peel ratio followed by CaCl2@4% compare to control. Maximum shelf life up to 20 days (2015-16), 19 days (2016-17) was recorded in fruits under GA3 @150 ppm treatment followed by CaCl2@4%, 18 days (2015-16), 19 days (2016-17) compare to minimum 13 days (2015-16), 12 days (2016-17) in control. Thus pre harvest application of GA3@ 150 ppm was an efficient method of delaying banana fruit ripening with better quality and it allows growers to schedule banana fruit ripening.
