Abstract
The cajazeira (Spondias mombin L.) is a stone tree belonging to the Anacardiaceae family is very common in the caatinga ecoregion of northeastern of Brazil. This study assessed the biometry of cajazeira stones stones. The stones were collected in 2019 within an area of native vegetation in the campus of the Federal Rural University of the Semi-arid Region (UFERSA), Mossoró-RN. They were then taken to the Plant Science Laboratory to measure the following characteristics: length, width, length/width ratio, stones thickness, and weight. The variables length, width, length/width ratio, thickness, and weight of the stones had a low range of variation and low values for relative variation, and therefore high coefficients of Pearson of correlation. The data of length, width, and thickness showed a moderate degree of symmetry and a symmetrical and mesocurtic distribution, while length/width ratio and stones weight had almost symmetrical and mesocurtic distributions. The variables length and width and width and thickness showed significant positive linear correlations. The biometric data of caja stones fitted in to the approximate normal distribution of probability.
Highlights
The cajazeira (Spondias mombin L.) it is a tree belonging to the family Anacardiaceae
The length, width, length/width ratio, thickness and weight of cashews presented a reasonable adjustment to the normal distribution of probabilities as well as a high total amplitude of variation, except the length/width ratio, as well as an optimum value for the coefficients of variation, except the weight, which showed a reasonable degree of homogeneity of these evaluated characteristics, including absolute and relative dispersion even though the values of the total amplitude being relatively high through the difference between the maximum and minimum values of the samples, and by the values of the standard deviations and by the calculation of the coefficients of variation, the length and the thickness being the less dispersed variables than the width, length/width ratio and the weight of the stones
The weight and width showed a strong adherence to the normal distribution of probabilities, evidenced by the histogram and frequency polygon as well as through the result of D’Agostino-Pearson’s normality test
Summary
The cajazeira (Spondias mombin L.) it is a tree belonging to the family Anacardiaceae. This species has hermaphrodite, staminate and pistillate flowers, with an apparent occurrence of protandry, which favors cross-pollination and genetic variability in orchards (Sacramento & Souza, 2000). The species is still very little cultivated on a commercial scale, being considered a plant in domestication and extractive exploitation. Even so, it has growing participation in the agribusiness of the Northeast region, mainly by the commercialization of its stones for pulp processing
