Caracterización morfológica y dasométrica de la especie amenazada Juglans pyriformis Liebm

juglans pyriformis is a threatened species endemic to a cloud forest environment. in order to determine the morphological variation within the j. pyriformis population in coacoatzintla, veracruz. six morphological and two dasometric variables were evaluated, through non-probability sampling, in 1 to 5 individuals per site, located at a distance equal to or greater than 50 m or until locating the next individual. the data were analyzed using tests of independence between variables, principal components analysis, cluster analysis, coefficient of variation and levene's test of homogeneity of variance. the results obtained allowed identifying two indicators for the crown and trunk morphological variables, and one for the height-diameter dasometric relationship. the height-diameter indicator provided more variation within the population (42 %). significant differences were found within the population for the crown and height-diameter indicators.
