ABSTRACT The aim of this work was to evaluate the effect of ethanol and two nitric oxide dose applications on the maintenance of the post-storage quality of ‘Galaxy’ apple during storage under controlled atmosphere (CA). Treatments evaluated were: [1] 1.2 kPa O2 + 2.0 kPa CO2; [2] CA + 20 µL L-1 of nitric oxide, [3] CA + 40 µL L-1 of nitric oxide; [4] CA + 1 ml of ethanol kg-1 fruit. Fruits received treatments before storage and were kept under CA during eight months and seven days of storage at 20 °C. Fruits had been kept on CA for eight months and seven days at 20° C. Fruits treated with ethanol showed higher ethylene production, low flesh firmness, high flesh breakdown, mealiness and acetaldehyde production. Fruits treated with 40 µL L-1 nitric oxide showed lower ethylene production, respiration rate and ACC oxidase ( (1-aminocyclopropane-1-carboxylic acid) oxidase enzyme activity. Apples treated with 20 uL L-1 nitric oxide showed higher ethylene production, respiration rate, internal ethylene concentration CO2 and ethanol concentration. Ethanol and nitric oxide application before storage have no benefits in maintaining fruit quality after storage under CA due to lower flesh firmness, higher mealiness incidence, flesh breakdown and decay incidence.
