Abstract
The effect of pre-storage application of calcium chloride (CaCl2) on chilling resistance and calcium (Ca) concentration of arils and peel of pomegranate (Punica granatum) Malas Saveh were determined.
The fruits were immersed in distilled water and two CaCl2 concentrations (135 and 270 mM) for 5 and 10 minutes.
The peel Ca concentration of treated fruits significantly increased after 2 months storage, but the arils Ca concentration was not affected with different treatments.
Chilling injury (CI) symptoms appeared after 2 months of storage.
Postharvest CaCl2 treatment limited the intense of peel CI symptoms such as browning and pitting but it had no significant effects on internal symptoms especially on segment separating thin layer browning.
Treated fruits with 135 and 270 mM CaCl2 reduced the ion leakage of peel up to 27 and 29%, respectively.
