Abstract : The goals of this study were to compare a growth model developed to the real growth of the measured fruits in the field using two values of initial relative growth rate, one established by literature and other estimated for each fruit, and to estimate inferior and superior basal temperature for fruits of 'Alpha' mango using the technique of artificial intelligence called as genetic algorithm. To accomplish the growth estimate, the used model considered the values of initial relative growth rate of the fruits, dry weight (current and maximum) and degree-days. In this work, 06 fruits of 'Alpha' mango were monitored until maturity, between August/2010 and January/2011, with average maturity of 103 days in a non-irrigated orchard of Experimental Farm of UFMT, in Santo Antônio do Leverger/MT. The best estimate of growth found when compared to the real growth of the measured fruits in the field was using the value of 0.0105 established for initial relative growth rate of mango fruits by literature and the values of 7°C for Tb and 41°C for TB.
