Palabras clave: branch dynamics, branch persistence, vitality (en_US)
Palabras clave: dinámica de ramas, persistencia de ramas, vitalidad (es_ES)

Resumen (es_ES)

Se describe un método de muestreo de tipo destructivo para estimar la edad de ramas de primer orden con aplicación en cualquier especie que presente verdaderos anillos anuales de crecimiento en árboles vivos. Su implementación requiere estimar el desarrollo de altura total de los árboles, utilizando técnicas de análisis de tallo y de la medición de la altura y ángulo de inserción para una muestra de ramas de primer orden. El procedimiento permite estimar la edad y año de formación de las ramas, el período de mantención de ramas vivas y de persistencia de ramas muertas en la copa de los árboles. Es un método alternativo al de disección de ramas. La implementación de algoritmos requeridos se ilustra detalladamente para un individuo de Nothofagus obliqua (Mirb) Oerst. (Fagales: Nothofagaceae) de 48 años de edad.

Resumen (en_US)

A destructive sampling method to estimate the age of first-order branches is presented. The proposed method can be applied only to living tree species showing annual growth rings. The implementation requires an estimate of total tree height development applying stem analysis techniques and the measurement of stem height and insertion angle for a sample of first-order branches. The developed procedure allows estimating the age and year of branch formation, and the maintenance of branches within the death and live crown. It can be considered an alternative to branch dissection methods. The algorithms’ implementation is illustrated for a 48-year old Nothofagus obliqua (Mirb.) Oerst. tree.
