Growth of Monilinia fructicola significantly declined with increased
CO2 concentration, both 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
and reached 92.8
l l-1
in 30% CO2 after 18 days at 0°C. CO2 concentration of 25¯30%
did not affect SSC and 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.
