ABSTRACT :
Apple fruits were infiltrated with 0, 2 or 4% CaC12 (cv. Golden Delicious) and 0, 4, 6 or 8% CaCl2 for 6 min at a pressure of 103 kPa. The fruits were then rinsed, dried with paper, packed in tray pack boxes and stored at 0 deg C for 5-6 months. All CaCl2 treatments significantly increased fruit Ca concentration compared with untreated controls and fruit firmness was positively related to fruit Ca concentration. Fruit Ca concentration and firmness both varied between orchards from which the fruits had been obtained. Golden Delicious fruits were more susceptible to skin injury caused by CaCl2 treatment than were Delicious fruits, which were still suitable for processing. Increased fruit decay incidence was also observed in treated fruits, possibly exacerbated by CaCl2 injury.
