Sažetak
Apple is the most common species in fruit production in Croatia and in the world. Application of fungicides on fruits after harvest is prohibited. The possibility of control of Penicillium expansum in apple cultivar ‘Braeburn’ by postahrvest heat treatment (hot water dipping at 48 °C for 12 min) was investigated. Fruit were infected with isolate ID-P3 of Penicillium expansum immediately after treatment and 24 hours after the treatment and placed in cold storage with a normal atmosphere at 0 °C. The first visible symptoms of infection appeared after 4 weeks. Measurements were performed at 0, 7, 14 and 28 days of the first symptoms of infection. The results show that there is a significant difference between control sample and thermal treatment of infection after 24 hours. For fruit there were no visible damage from the heat treatment. The results show that heat treatment stimulates the defense mechanism of the fruit. In order to promote this research is necessary to examine other environmentally- friendly treatments.
