Mango is a species from India, currently spread over nearly all tropical regions of the world, being grown commercially also in some regions of subtropical climate. The interest in the crop is due to the excellence of the fruit, which, besides presenting exotic flavor, is rich in vitamins and minerals, being one of the richest fruits in vitamin A. The objective of this work was to study the effect of different temperatures of ethylene application on the mango 'Tommy Atkins quality. The treatments were: T1 = fruits stored under uncontrolled conditions (24ºC ± 5°C and 65% RH) and without ethylene (control), T2 = fruits under uncontrolled conditions - with 25 ppm ethylene for 2 days (24ºC ± 5ºC and 65% RH), T3 = fruits at a temperature of 16°C ± 1ºC and 90% RH, with 25 ppm ethylene for 2 days, T4 = fruits at a temperature of 18°C ± 1 º C and 90% RH, with 25 ppm ethylene for 2 days, T5 = fruits at a temperature of 20°C ± 1ºC and 90% RH, with 25 ppm ethylene for 2 days, T6 = fruits at a temperature of 22°C ± 1 º C and 90% RH, with 25 ppm ethylene for 2 days and T7 = fruits at a temperature of 24°C ± 1 º C and 90% RH, with 25 ppm ethylene for 2 days. After treatment, fruits were stored at 20°C ± 1ºC and 90% RH (T3 and T7) and uncontrolled environmental conditions (24ºC ± 5°C and 65% RH) in T1 and T2, for 14 days. Fruits were characterized at harvest and after treatment, 0, 7th and 14th days. Soluble solids, acidity, skin colour and pulp colour, manual firmness of fruits and rot. It was concluded that the temperature of 20°C, can be suggested for the application of exogenous ethylene for uniform ripening on mango 'Tommy Atkins'.
