Effect of different levels of gibberellic acid and kinetin on quality and self-life of banana (Musa spp.) fruits

Artificial fruit ripening agents have become increasingly popular in recent years. During the off-seasons, various ripening agents are used for the ripening of banana fruits. The effects of various ripening agents of banana fruits (variety: Malbhog) were studied. Seven treatments consisting of distilled water, Gibberellic acid (GA3) @ 100 ppm, GA3 @ 200 ppm, GA3 @ 300 ppm, kinetin @ 3 ppm, kinetin @ 5 ppm, and kinetin @ 7 ppm were laid out in a Completely Randomized Design with three replications. The maximum loss in weight (9.195%), Total Soluble Solids (20.33˚B), the highest color score (6), pH (4.767), Total Soluble Solids/Titratable Acidity TA (34.23), and Pulp peel ratio (2.84) were observed in banana sprayed with distilled water whereas the minimum value for TSS (12.67˚B), pulp peel ratio (1.813), peel color rating (2.67), TSS/TA (15.32) were observed in GA3 @ 300 ppm treated fruits. The maximum (32.67 days) and the minimum (18.33 days) shelf-life was observed in GA3 @ 300 ppm and distilled water respectively. This research will help in the regulation of ripening as per the needs of consumers and the distance of the market. In horticulture, it will help to extend storage life and reduce quality and economic loss.
