Conteúdo: 	THE OBJECTIVE of controlled-atmosphere (CA) storage of fruits is to prolong storage life through respiratory control. Lowering atmospheric oxygen (O2) decreased respiration of Valencia oranges (Chace et al., 1967), but after 12 wk in 5 and 10% O2, the oranges developd distinct off-flavors and high concentrations of ethanol. Anaerobic metabolism produced ethanol in fruits (Wilkinson, 1970), and may also produce off-flavors. Increasing carbon dioxide (CO2) concentrations in storage gas has improved quality of many stored fruit, and depression of aerobic and anaerobic respiration of plant tissue by CO2 has been documented (Smith, 1963). However, CO2 at 2.5 and 5% did not improve flavor of Valencia oranges stored under 5 and 10% O2 (Chance et al., 1967), and Youn g and Biale (1968) reported  stimulation of respiration in lemons by 5 and 10% CO2 with 21% O2. Relating various O2 -CO2 combinations to biochemical changes in citrus fruits would form a rational basis for optimizing  conditions for CA storage, and it is toward this end the present work was directed.
