Effect of low O2, high CO2 or added acetaldehyde and ethanol on postharvest physiology of cherries.

Fruits of sweet cherry (Prunus avium) cv. Van were harvested on 4 or 17 (commercial harvest date) June [year not given] from an experimental orchard at Bilje, Slovenia, and held at 20 deg C in parafilm-covered jars in 100% CO2, 100% N2, acetaldehyde (AA) vapours, ethanol (ET) vapours or air for 24 h. Fruits were subsequently transferred to air at 0 deg C. AA and ET accumulated much more rapidly during ripening in fruits held in CO2, N2, AA vapours and ET vapours than in control (air-stored) fruits. More AA and ET accumulated in mature fruits (harvested on 17 June) than in less mature fruits. AA or ET vapours caused an increase in AA and ET concentrations in fruit tissue. Exposure of fruits to AA or ET vapours did not influence fruit ripening. However, short exposure of cherries to CO2 or N2 atmospheres inhibited ripening of fruits (maintained fruit firmness) and thus prolonged their storage life. AA and ET also slowed the increase in a colour value of fruits, indicating that they inhibited antho

cyanin formation.
