Differences in the storage potential of apple cultivars caused by various postharvest calcium infiltration methods.

Fruits of 3 apple cultivars were subjected to postharvest treatment with 0, 2, 4 or 6% CaCl2 by dipping or pressure (80 kPa) or vacuum (40 kPa) infiltration then stored at 4 deg C for 1-7 months followed by 20 deg for 1-2 weeks. Flesh firmness during storage was not affected in cv. Tsugaru, but in cultivars Jonathan and Fuji, firmness was increased with pressure or vacuum infiltration but not with dipping. In Jonathan, but not in Fuji, the firmness tended to increase with increasing Ca concentration, and was higher with vacuum than with pressure infiltration. In cv. Fuji, firmness was slightly higher with pressure than with vacuum infiltration. A higher infiltration force (100 or 48 kPa for pressure and vacuum infiltration, respectively) tended to give greater firmness in Fuji but not in Jonathan. Treatments had no effects on fruit soluble solids contents or total acidity.
