Physiological Changes of Different Varieties of Sapota at Ambient Storage

The investigation was conducted to evaluate physiological changes of different varieties of sapota at ambient storage. Fifteen varieties viz. Kalipatti, Cricket Ball, DHS-1, DHS-1 selection, DHS-2, PKM1, PKM-3, PKM-4, CO-1, CO-2, CO-3, Virudhunagar, Kirthibarti, Cricket Ball selection (ARS-A) and Cricket Ball (Udupi) were studied under Ghataprabha command area conditions. The variety Cricket Ball (Udupi), PKM-4, Cricket Ball Selection (ARSA), DHS-1 selection and CO-1 recorded minimum physiological loss in weight and maximum was recorded in Virudhunagar and DHS-1. The respiration of Cricket Ball, PKM-1, PKM-4, Virudhunagar, Kirthibarthi, Cricket Ball (Udupi) reach respiration peak at 2 DAS, Kalipatti, DHS-2, PKM-3, CO-2, CO-3, Cricket Ball selection (ARSA) reached respiration peak at 4 DAS. The hybrid DHS1, DHS-1 selection and CO-1 reached respiration peak at 6 DAS. Throughout the storage period, the variety DHS-1, DHS-1 selection and CO-1 showed minimum ripening per cent representing delay in ripening change. Among the varieties, CO-2, DHS-2 and DHS-1 selection noticed lowest decay per cent. However, Virudhunagar recorded highest decay percent during storage. Maximum shelf life was recorded in DHS-1, DHS-1 selection and CO-1 (10.00 days each) followed by Cricket Ball, DHS-2, PKM-3 and PKM-4 (8.50 days each). However, minimum was noticed in Virudhunagar (6.00 days).
