Abstract

Summary Apples of the cultivar 'Summerred', grown in Norway (59°40'N), were harvested in September and stored in controlled atmosphere (CA) at 3% O 2 + 3% CO 2 or in normal air (NA) at 2°C until the middle of January. After removal from storage in December and January, the apples were kept one week at room temperature, simulating shelf-life. There were only small or no differences in fruit quality between the two storage methods. Principal component analysis (PCA) of shelf-life samples revealed three components explaining 87% of the total variation. The most important cause of variation were the storage methods (41% explained), followed by storage period (31% explained) and the variation caused by year of harvest (15% explained). Beneficial effects of CA-storage for 'Summerred'- apples were of minor importance and therefore they cannot justify the cost of CA-storage.
