Abstract :
The experiment was conducted to evaluate the effect of different postharvest treatments on physical changes and on shelf life of banana during storage. There were seven treatments viz., control (T0), perforated polythene (T1), non-perforated polythene (T2), benzyl adenine (BA) (T3), gibberellic acid (GA3) (T4), benzyl adenine (BA) + 15°C (T5) and gibberellic acid (GA3) + 15°C (T6) and two varieties of banana var. Amritasagar (VI) and Sabri (V2). The two-factor experiment was laid out in completely randomized design (CRD) with three replications. Among the physical parameters such as total weight loss, pulp to peel ratio, moisture content, dry matter content. Gibberellic acid (GA3) + 15°C treated banana fruits showed minimum (6.41%). The effect of postharvest treatments and variety were not significant in relation to percent dry matter content at all days of storage. The postharvest treatments showed highly significant variation in respect of shelf life among the treated and untreated bananas. GA3 + 15°C, BA + 15°C, GA3 and BA treatments exhibited better storage performance. The variety Sabri treated with GA3 + 15°C showed the longest shelf life (14.67 days) followed by BA + 15°C treatment (13.65 days). The study revealed that GA3 + 15°C treatment found minimum weight loss, pulp to peel ratio, percent moisture content and percent dry matter content.
