SOUZA, Jaqueline Lima da Conceição et al. Physical and chemical characterization of gabiroba and murici. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.3, pp.221-230. ISSN 0871-018X.  https://doi.org/10.19084/rca.17521.

The knowledge of the physical and chemical characteristics of the fruits of the Cerrado is important, from the commercial point of view, to add value and quality to the final product. The objective of this study was to evaluate the physical and chemical characteristics of gabiroba fruits (Campomanesia adamantium (Cambess.) O. Berg) and murici (Byrsonima verbascifolia (L.) Rich). Twelve fruits per matrix were collected in 12 matrices for both species. The physical characteristics evaluated in fruits and seeds were: longitudinal and transverse diameter, and mass. The chemical characteristics studied were: pH, soluble solids, acidity in citric acid, humidity and ashes. Fruits of gabiroba had average values ​​of: longitudinal diameter (13.99 mm); transverse (14.40 mm); mass of the fruit (2.359 g); pH (3.767); soluble solids (11.78°Brix); acidity in citric acid (11.20 mg g^-1), humidity (78.24%); and ashes (21.40%). It was observed that the physical variables evaluated in fruits of murici obtained the respective values ​​for longitudinal diameter (14.53 mm); transverse (15.36 mm); and mass of the fruit (2.61 g). The fruits produced by gabiroba and murici matrices showed that there is intrapopulational variation among the physical and chemical variables evaluated, existing plants with superior agronomic characteristics and promising to genetic improvement through selection practice.
