Therefore, this study was carried out to examine the response of ?Luiza? apple to different storage atmospheres, durations, and the chemical inhibition of ethylene action (1-MCP). Three experiments were carried out over three growing seasons to evaluate the storability of ?Luiza? apple in cold air or controlled atmosphere storage (CA) with and without 1-MCP (Exp 1); the effect of harvest time (Exp 2) and varying CO2 partial pressure (Exp 3) (&lt0.5-4.5 kPa CO2). Analysis of fruit quality and physiological disorder incidence were performed every two months during eight months of storage for Exp 1 and 2, and after eight months for Exp 3. Both CA storage and 1-MCP treatment reduced fruit ethylene production and respiration and prevented the rapid softening of fruit, flesh browning incidence and fungal decay of ?Luiza? apple. The combination of 1-MCP treatment at harvest then storage in CA provided an additional benefit in firmness retention after simulated marketing conditions at 22oC for one week. Based on the time to reach a firmness of 53 N, the storage life of ?Luiza? apple is less than four months in Air-storage and more than six months under CA-storage. ?Luiza? fruit did not develop symptoms of CO2 injury when stored under high CO2 partial pressures (up to 4.5 kPa).  However, we observed increased flesh browning and fungal decay incidence for CA-stored fruit between six and eight months of storage. Thus, the storage potential of ?Luiza? apple fruit may be limited to six months under CA-storage (1.5 kPa O2 and 2.5 kPa CO2) based on incidence of flesh browning. These results can guide recommendations to the apple industry regarding the best storage practices for the new apple cultivar ?Luiza?.  adecay  aflesh browning  aflesh firmness  aMalus ?? domestica Borkh  astorability1 aANESE, R.
