EFECTO DEL APROVECHAMIENTO FORESTAL SOBRE LA VARIACIÓN MORFOLÓGICA DE Juglans pyriformis LIEBM.

Abstract

El aprovechamiento forestal basado en la extracción de individuos fenotípicamente superiores, al igual que otros factores, podría hacer degenerar el bosque al dejar árboles de menor calidad y disminuir la diversidad genética. La población de Juglans pyriformis en San José Buenavista, Veracruz (SJB), ha sido reducida por actividades agropecuarias y aprovechamiento forestal con fines maderables bajo el método silvícola de Selección Individual, mientras que la población de Coacoatzintla, Veracruz (COA), se ha reducido por cambios de uso de suelo y explotación clandestina. El objetivo fue determinar los niveles de variación fenotípica de J. pyriformis en SJB y contrastarla con la variación encontrada en la población de COA en un estudio previo, utilizando la misma metodología. En SJB el análisis de componentes principales identificó tres indicadores, FUSTE, COPA y ALT-DIAM, con un coeficiente de variación alto 26, 30 y 42 % respectivamente. El análisis de conglomerados mostró dos grupos de árboles, y el estadístico de Levene fue significativo (P<0.05) para el indicador COPA (0.030) y ALT-DIAM (0.161). Los resultados muestran una menor variación morfológica en la población de San José Buenavista en contraste con la población de Coacoatzintla.
