OLIVA-HERNANDEZ, Jorge; LOPEZ HERRERA, María Aurelia  and  CASTILLO LINARES, Erika Belem. Relationship between morphological measurements of trunk in Erythrina americana Miller and yield of edible foliage.

The aim of this study was to analyze the relationship of diameter and height of Erythrina americana tree with the foliage yield at a regrowth age of 90 days. Forty-seven trees with height of 1.6 m ± 0.2 m, diameters of 0.085 ± 0.021 and 0.065 ± 0.018 at a height of 0.20 m and 1.3 m from soil respectively were used. The relationship between height and diameters of the tree with the dry matter yield (DMY) tree-1 was determined with correlation process. The variation in DMY tree-1 was determined through multiple regression. Tree height and diameters at 0.20 and 1.3 m had a positive relationship with DMY tree-1 (p < 0.05 and p < 0.001, respectively). The diameter of the tree at 0.20 m explained 34% of the variation in DMY tree-1 (p < 0.001). Tree height and diameter did not have an important predictive value in DMY tree-1.
