Abstract

Urucum (Bixa orellana L.) is a shrub plant occurring in the caatinga biome. This study evaluated the biometrical assessment of quantitative features of Urucum in northeastern Brazil. Fruit samples were taken from an area of native vegetation of the Federal Rural Semi-Arid University (UFERSA), Mossoró, RN. Measurements on seed length and width of fruit samples were done at the plant science laboratory. Descriptive and graphical analysis were carried out using the R statistical software. Seed length and width showed a small range of variation with an excellent and reasonable values of coefficient of variation, respectively. A regular degree of symmetry and a mesokurtic distribution were observed for seed length and width. There was non-significant linear correlation between both variables which did not fit to the normal probability distribution.
