Abstract: The pequi, native fruit of the Cerrado, presents alimentary use with great potential for expansion in Brazilian cuisine, being appreciated for its pleasing color, aroma and flavor peculiarities. The specie is widely distributed in the Brazilian cerrado taking important role in the lives of the inhabitants of this region, economically, with the sale of the fruit in natura, or even for their own consumption. In this project were evaluated the use of the nonlinear models Brody, Gompertz, Logistic and von Bertalanffy considering independent errors and first order autoregressive errors, in the growth description of the pequi fruit in diameter and mass increase over its development. Brody model has not converged for the pequi fruit weight gain data. Gompertz, Logistic and von Bertalanffy models obtained good fits, and the Gompertz model obtained a better fit to mass increase data according to the adjustment quality evaluators. Regarding the increase in longitudinal diameter and transverse diameter, all models converged and achieved good adjustments. The von Bertalanffy model was considered the most suitable in both cases according to the adjustment quality evaluators.
