Abstract: Changes of water soluble calcium in banana (Musa acuminata cv. ‘Dwarf Davendish’) fruits during ripening were studied to determine the relationship between internal calcium changes and Postharvest, respiration.The effects of calaium on Postharvest respiratory characteristics of banana fruits were determined by vacuum infiltration with solutions containing calcium chloride. The results showed that water soluble calcium in both banana Peel and pulp increased with ripeness, especially at the onset of respiration climacteric rise. The appearance of climacteric peak was delayed in banana fruits infiltrated with 0.05 mol/l and 0.1 mol/1 calcium chloride. The results suggest that the increasing of water soluble calcium is a stimulative at the onset of respiratory climacteric, and that calcium treatment reduces both the ethylene level in fruit tissues and the sensitivity to endogenous ethylene, thus delaying the aPPearance of clima-cteric peak.
