Preclimacteric `Empire' apples are prone to develop a CO2-linked disorder (CLD); the symptoms resemble superficial scald. Effects of acclimatizing preclimacteric fruit at 3°C, either in air or at low O2 levels prior to elevation of the CO2 concentration during subsequent long-term controlled atmosphere (CA) storage, were investigated. The `Empire' CLD was effectively controlled by conditioning fruit at 3°C (but not at 0°C) for 3¯4 weeks at 1.5¯3% O2 without CO2 prior to CA storage at 1.5% O2+3% CO2. Reduction of the disorder was also achieved by storage at 3°C in air, but excessive ripening and associated loss of flesh firmness occurred during subsequent CA storage.
