Changes in postharvest physiology in relation to the incidence of CA disorders during CA storage of 'Fuji' apples.

 

Apples were harvested twice at 14-day intervals; early-harvested apples were stored in a controlled atmosphere (CA; 1-2% CO2 + 2-3% O2) immediately after harvest (standard CA), while late-harvested apples were stored in air, in standard CA or in CA after 4 weeks in air at 0 deg C (delayed CA). Fruits were removed from the store at 15-day intervals and their metabolic rates were evaluated. The incidence and the severity of browning symptoms were higher in standard CA fruits than in delayed CA fruits, while fruits stored in air were mostly sound. Standard CA fruits showed relatively lower rates of respiration and ethylene evolution than air-stored apples. In delayed CA apples, the metabolic rates were similar to standard CA fruits during the early storage period, but they subsequently increased. ACC (1-aminocyclopropane-1-carboxylic acid) contents of air-stored apples tended to increase and became higher than those in standard CA and delayed CA fruits towards the end of the storage period. Ethanol

 production increased in CA-stored apples until after 60-75 days of storage, when it sharply decreased, while ethanol production in air-stored fruits remained at a relatively low level throughout. Data partially supported the theory that retained potential of energy metabolism during storage might reduce the susceptibility to internal browning.
