Mathematical models for describing growth in peach (Prunus persica [L.] Batsch.) fruit cv. Dorado

Among deciduous species, the peach tree (Prunus persica [L.] Batsch.) is of great importance in high tropics. However, growth behavior this fruit for different cultivated varieties unknown. So, adjustment to double sigmoid curves assumed all even though type have been reported many cultivar. This has led misinterpretation information, impeding decision-making terms management. Non-linear regression models best describe curves, where parameters are estimated by minimizing sum squares errors. In particular, logistic model one better options correctly representing growth. Therefore, objective research was determine efficiency mathematical describing P. cv. Dorado fruits grown under conditions municipality Tuta-Boyaca. The Logistic most appropriate based on fresh or dry weight, while Gompertz suitable polar and equatorial diameters variety because they were used generate these with practical interpretations adequately represented biological process.
