MORPHOMETRIC CHARACTERIZATION OF NANCHE (<em>Byrsonima crassifolia</em> (L.) H.B.K.) FRUIT AND SEEDS

The objective of the paper was to morphologically characterize the fruits and seeds of 23 collections of nanche (Byrsonima crassifolia (L.) H.B.K.), that originated in the state of Tabasco, Mexico. Twenty-two digitalized characters were measured with an image analyzer for the description. The data obtained were analyzed with SAS and NTSYS programs. Three main components explained 84.16% of the total variability. Five groups were defined in the dendrogram, with a Euclidian distance of 5.58. Group I has fruit with the highest Brix degrees and percentage of pulp; Group III has the fruit with the highest area, longitude of the main axis, longitude of the lesser axis, Feret’s diameter, weight, pulp thickness, pulp weight, dry weight values and HUE value. Group IV has the highest luminosity (L) and croma (C) values. Group V has the highest volume of 25 fruits. These results demonstrate the diversity of nanche that exists in Tabasco, Mexico. The information may therefore be useful for the selection of germplasm.
