AB  - Calcium content and damage severity of <i>Penicillium expansum</i> because of its high concentration on “Red Delicious” postharvest apples were evaluated during the 2012-2013 winter in Cuauhtemoc, Chih. Mexico. Fruit weight, diameter, total soluble solids, pulp firmness and starch index were also determined. <i>Penicillium expansum</i> was inoculated into two wounds of eight mm diameter and 10 mm depth, on a total of 20 apple fruits per treatment. The inoculum was 0.2 mL of a suspension containing 1×10<sup>8</sup> conidia/mL. After inoculation, apple fruit was stored at 0 °C and 90% relative humidity during five weeks. Treatments were: apple fruit with high (2.28 mg/100 g fresh weight) and low (2.16 mg/100 g fresh weight) calcium content, with and without <i>P. expansum</i>, and a control which was inoculated with sterile water. The greater the fruit Ca content, the lower the severity of the fruit area affected by <i>P. expansum</i> (i.e., 27 cm2 affected with high Ca content vs. 34 cm2 with low Ca content).
