The history of controlled atmosphere (CA) storage of apples is reviewed and future prospects are outlined. Control of CO2 concentration by ventilation with fresh air (ventilated CA) was an early simple method of storage, which proved to be adequate for some cultivars. Subsequently low-O2 and ULO (ultra low oxygen) storage techniques were developed for cultivars that were either intolerant of, or derived no benefit from, increased external concentration of CO2. State-of-the-art CA storage facilities that maintain appropriate storage conditions exist in many countries. The recommended atmospheres of O2 and CO2 are approaching the limits of tolerance of stored apples and it is unlikely that there will be benefit from further adjustment of conditions without risking damage to the fruit. It can be expected that there will be some development of adaptive CA which optimizes the store conditions in line with physiological indicators in the stored fruits such as ethanol production or change in respirator

y quotient, which will be particularly useful for ensuring that individual consignments of fruit are stored in the most appropriate conditions. Further research is required to identify a physiological state which balances the negative aspects of O2 and CO2 stress (which include reduced synthesis of aroma compounds and increased susceptibility to chilling injury and corking disorders) with the positive effects on reduced rate of senescence and improved quality retention. A major influence on the choice of CA conditions is the susceptibility of particular cultivars to superficial scald.
