Biometry of the Characteristics of Cajazeira (Spondias mombin L.) Stone in Northeast Brazil

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.
