Injured apple fruit cultivars (Gala and Fuji) were subjected to the following treatments: dipping in clean water; dipping in water with Penicillium spores; dipping in water with Penicillium spores + 30 h exposure of fruits to 20 deg C; storage for 30 h at 20 deg C + dipping in water with Penicillium spores; and dipping in 1.5% Ca(OH)2 or 1.5% Cacl2 before storing at 0 deg C for Gala and -0.5 deg for Fuji. Rot incidence was evaluated after 60 days and after 7 and 14 days of shelf life at 20 deg C. Rot incidence was not observed in fruits dipped in Ca(OH)2 and CaCl2, with Ca(OH)2 being more efficient in preventing rot incidence in Gala. Fruits maintained at 20 deg C for 30 h before inoculation with spore solution, showed less rot incidence than fruits inoculated immediately after injury. Fruits dipped in clean water had lower rot incidence than fruits dipped in spore solution.
