Résumé

Growth of Monilinia fructicola significantly declined with increased CO2 concentration, in vitro and in vivo. CO2 concentrations at 15-25%, provided a significant reduction in lesion size and, at 30%, completely prevented lesion formation at 25 °C. Low temperature also inhibited growth and pathogenicity of M. fructicola. The fungus was more sensitive to high CO2 concentrations at 0 °C. Fungal growth on PDA was completely suppressed and brown rot was not found in inoculation sites on fruits in 10-30% CO2 after 30 days at 0 °C. Low temperature reduced ethylene production more than elevated CO2. Fruit ethanol content increased with increasing CO2 concentration. CO2 concentration of 25-30% did not affect pH, but increased firmness, vitamin C content and titratable acidity. No high CO2 injury or off-flavors were noted after 18 days at 0 °C for sweet cherries at any CO2 level tested.
