Melons (cv. Orange Flesh) were dipped in 2% CaCl2 at 50 deg C for 20 minutes and then stored for up to 28 days at ambient temperature or up to 31 days at 6 deg C, 85% RH. Fruits dipped in CaCl2 and stored at ambient temperature had higher contents of cell-wall-bound Ca and pectic substances and lower cell-wall protein content than control fruits not dipped in CaCl2 and stored at ambient temperature. After 28 days' storage at ambient temperature, cellulose, protein and pectin contents were lower, polyuronide and cell-wall-bound Ca contents were higher and hemicellulose content was the same (in both control and CaCl2-treated fruits) as levels found in freshly harvested fruits. CaCl2 treatment increased cell-wall-bound Ca and polyuronide contents in fruits stored at 6 deg C.
