✦ Synopsis

The in¯uence of cultivar on responses of strawberry fruit to 20 kPa CO 2 or air storage at 2 °C was measured for 7 days. CO 2 storage increased ®rmness of all cultivars over air storage, but the degree of increase was affected by cultivar and days in storage. CO 2 -treated fruit were lighter colored and less intensely red than air-treated fruit. Accumulations of acetaldehyde, ethanol and ethyl acetate in CO 2 -treated fruit were strongly affected by cultivar, with those in Annapolis' having the lowest and those in Governor Simcoe' having the highest concentrations. Genetic variation in this response provides useful material for investigating the metabolic basis of CO 2 effects in strawberry fruit.
