Effect of physico-chemical treatments on ripening behavior and post- harvest quality of Amrapali mango (Mangifera indica L.) during storage.

ABSTRACT

An experiment was done to assess the effect of various physico-chemical treatments on ripening behavior and post harvest quality of mango cv. Amrapali. The experiment was planned under completely randomized design (CRD ) with three replications. The treatment units was five fruits per replication. Total 14 treatments were applied. Out of these, ethrel 750 ppm treated fruits showed better results in respect of specific gravity (0.88), moisture loss (8.45%), decay (2.5%), total soluble solids (TSS, 20.7o brix), sugar content (14.39%) and acidity content (0.32) followed by ethrel 500 ppm; specific gravity (0.90), moisture loss (8.82%), decay (3.5%), TSS (20.7o brix ), sugar content (13.99%) and acidity content (0.36%). The pedicellate fruits and ethrel+bavistin (750+1000 ppm) were also found to be significantly superior over control in respect of specific gravity (0.88 and 0.86), moisture loss (9.10 and 9.33%), decay (4.0 and 5.33%), TSS (20.1 and 20.4o brix), sugar content (12.70 and 12.80%) and acidity content (0.42 and 0.38%), respectively. Based on results of this study, it can be concluded that ethrel 750 ppm was found to be the most suitable treatment in improving physico-chemical traits i.e. ripening, storage, quality and shelf-life for commercial purpose in mango.
