Caracterización de la semilla de guamúchil Pithecellobium dulce (Roxb.) Benth

The characterization studies in seeds are of interest and importance for any genetic improvement program of the low deciduousforest. To carry out this research, 34 localities from three states of the Mexican Republic were considered: Guerrero, Morelos andthe State of Mexico, they were separated into groups which were: G. Dulce, Dulce, G. Amargo, Amargo, G. Simple, Simple andseveral in the latter find two localities that presented 5 different genotypes, 10 seeds were randomly selected per genotype. Theobjective was to characterize the seeds of guamúchil in different regions, to obtain information regarding this tree, as well as togenerate trees with desirable characteristics; Measurements were carried out with a mitutoyo vernier for the length, width andthickness of the seed, the weight was determined with a precision balance. Analysis of variance, comparison of means, wereperformed to detect differences between genotypes. No significant differences were found in the variables. However, the genotypesthat presented the highest value in the mean for the length was G. Dulce from Chilapa de Álvarez, Gro., While the width was fromthe Bitter genotype that was collected from Alpuyeca, Mor., In the thickness of found in the G. Dulce genotype from Tlapa, Gro.,and the highest weight was of the Amargo genotype from the town of Zumpango del Río, Gro.
