| Abstract Pequi tree is a species native to the Brazilian cerrado, with wide geographic distribution, whose fruit is very appreciated in cooking, composing traditional dishes. In general, pequi fruit is consumed when ripe in the fresh form or in the various derived products such as oils, liqueurs, sweets, ice creams among others, involving important socioeconomic activity generating employment and income in family agriculture. The aim of this study was to evaluate the adjustment of Brody, Gompertz, Logistic and Von Bertalanffy models in the growth and development of pequi fruits based on their physical characteristics such as longitudinal and cross-sectional diameter and fresh mass obtained over time. Parameters were estimated using R software routines,... |

| Abstract: The objective of this work was to estimate the phenotypic diversity in Jafarabadi, Murrah, and Mediterranean buffalo cows (Bubalus bubalis). Thoracic perimeter, withers-and-rump height, body length, and biiliac, external biischiatic, external ilioischiatic, sacropubic, and mean biiliac diameters were measured. The following indexes were calculated: anamorphosis index, pelvic index, withers-to-rump ratio, body index, lateral-body index, relative body index, body capacity indexes 1 and 2, transversal pelvic index, longitudinal pelvic index, and thoracic-perimeter-to-withers ratio index. The effect of breed was evaluated using univariate (mean tests) and multivariate (size-free discriminant analysis and Fisher’s linear discriminant function)... |

| ABSTRACT: The goal of this study was to elucidate the growth and development of the Asian pear fruit, on the grounds of length, diameter and fresh weight determined over time, using the non-linear Gompertz and Logistic models. The specifications of the models were assessed utilizing the R statistical software, via the least squares method and iterative Gauss-Newton process (DRAPER & SMITH, 2014). The residual standard deviation, adjusted coefficient of determination and the Akaike information criterion were used to compare the models. The residual correlations, observed in the data for length and diameter, were modeled using the second-order regression process to render the residuals independent. The logistic model was highly suitable in demonstrating... |
