The banana cv. Nanicão is the main cultivated and marketed in the Brazilian and world markets. Most of this banana marketed in the State of Mato Grosso comes from another States, and Mato Grosso presents edaphoclimatic conditions to be sufficient in the production of this cultivar and besides to assist other markets. The objective of this work it was to verify the conditions of the climatization of bananas cv. Nanicão and its influence in the post harvest conservation of fruits produced in Mato Grosso (MT) and coming from Santa Catarina State (SC). Twelve boxes were accompanied, weighting around 21 kg of bananas cv. Nanicão picked in the municipal district of Campo Verde-MT, in commercial orchard and also 12 boxes originated from SC. Previously of the climatization period, and during the whole period of useful life of the fruits, the temperature and relative humidity, the evolution of the coloration of the fruits and their weight loss, the total soluble solids and titratable acidity in the green and mature fruits were monitored. The largest period of useful life of banana coming from SC was verified, 3 day after the retreat of the climatization camera, turning totally yellow and with maximum values of 7,07% of loss of fruit weight. The banana cv. Nanicão produced in MT reached values of weight loss 5,69% in the 2nd day, when after that period it would not be appropriated for commercialization. The coloration of the fruits developed to yellow, and in some bunches they continued with green points, while other already began the senescence (brown points), being this smaller difference in bananas of MT, which reached a paler yellow coloration. These alterations can be related, respectively, with the lack of efficient circulation of the ethylene and the low relative humidity, around 65%, during the climatization.
