Quality indicators in nanche (Byrsonima crassifolia L.) fruits from Guerrero and Chiapas, Mexico

The nanche (Byrsonima crassifolia) is a wild, rustic and native plant of Mexico and Central America, it adapts to different edaphic and climatic conditions. The objective was to analyze the quality indicators of the nanche fruits of Guerrero and Chiapas. Completely random samplings were carried out in three and two localities of Guerrero and Chiapas, respectively, in 5 trees of each locality, collecting 50fruits per tree. The indicators analyzed were: fruit weight, fruit density, polar and equatorial diameter, oBrix, firmness, epidermis thickness, pulp weight, seed weight, luminosity, chromaticity and hue. The correlation between equatorial diameter/weight and lightness/chroma with r 2 of 0.93. Localities of Guerrero with greater statistical difference: Paso del Real was in weight, equatorial diameter; epidermis and seed. The fruits from Las Tunas were outstanding in oBrix, hue and seed weight, and those from San Jerónimo, Guerrero, recorded higher fruit density and equatorial diameter. The localities of Chiapas with the greatest statistical differences: Santo Domingo in density, polar diameter, firmness and pulp, and Mixiquito in fruit density and luminosity. It is concluded that the quality indicators of the nanche fruits collected in Guerrero and Chiapas have a wide distribution and decision making in the selection of trees with specific characteristics.
