Abstract: The growth of plants and animals can be described through a growth curve. This curve is given by the equation of a nonlinear model, such as the Logistic model and the Gompertz model. The objective of this study was to adjust the Chanter model, as well as Logistic and Gompertz, using a set of cocoa (clone Sial-105) fruit whose length and diameter measurements were evaluated from 30 to 180 days after pollination, every 15 days. The Chanter model is a hybrid between the Logistic model and Gompertz model whose par… Show more

“…The logistic model, and the double logistic and hybrid models such as chanter (logistic + Gompertz), have been used for modeling fruit growth in cacao 3 and various productive systems such as kiwi, coffee, and cashew. 11,[18][19][20] The cacao fruit development has been characterized by an early exponential growth, followed by a linear phase, and stabilizing in the ripening state. The fruit variables measured over time confirmed this behavior in the evaluated clones and facilitated the biological interpretation of the parameters obtained by the different models.…”
