Abstract
Physiologically mature, uniform fruits were thoroughly washed and dipped in aqueous solution of T0 (Untreated fruits), T1 (Boric acid at 200 ppm), T2 (Boric acid at 300 ppm), T3 (NAA at 100 ppm), T4 (NAA at 200 ppm), T5 (Salicylic acid at 300ppm), T6 (Salicylic acid at 400ppm) for five minutes. Fruits were placed in plastic trays and stored at ambient storage conditions for 12 days. The readings were observed after 4rd, 8th and 12th days. Physiological weight loss of fruits decreased with storage, further fruits treated with boric acid 300ppm recorded lower Physiological weight loss as compared to other treatments. Total Soluble Solids (TSS), Sugars were increased upto 12 days of storage.
