Selección de árboles semilleros de Alnus acuminata Kunth en los Andes del norte peruano

Abstract

La restauración de ecosistemas altoandinos requiere material genético adaptado y trazable para garantizar impactos sostenibles frente al cambio climático. Este estudio tuvo como objetivo identificar y seleccionar árboles semilleros de Alnus acuminata con base en atributos fenotípicos en una región de los Andes del norte peruano, a través de criterios morfológicos, dasométricos, sanitarios y de calidad de semillas. Se evaluaron 204 árboles en 18 localidades, se seleccionaron 34 individuos arbóreos semilleros mediante un sistema de puntuación, cuya consistencia fue evaluada con la prueba de rangos con signo de Wilcoxon (p<0.001). Las semillas presentaron alta calidad física y fisiológica, con pureza promedio de 81.51 % y germinación de 82.64 % y tiempo medio de emergencia de 11 días. El análisis de conglomerados K‑medias (K=3) y ANOVA (p<0.001) identificaron tres grupos fenotípicos diferenciados en tamaño y volumen, lo que permite definir clases productivas con aplicación en programas de restauración y mejoramiento genético. Las correlaciones entre germinación y variables ambientales fueron bajas, lo que sugiere influencia limitada de estos factores. Estos hallazgos validan la consistencia del criterio de selección y evidencian el potencial de los árboles semilleros para producir material forestal de reproducción (MFR) con trazabilidad y calidad homogénea, contribuyendo a la sostenibilidad y resiliencia de los bosques andinos.
