Evolución del crecimiento radial en un rodal adulto de Pinus nigra Arn. de la provincia de Lleida

Abstract

Se ha estudiado un rodal adulto (edad media = 139 años) de Pinus nigra ssp. salzmannii var. pyrenaica en el W de la comarca del Solsonès (Lérida). Se han medido y extraído testigos de madera de 97 árboles adultos, a partir de los cuales se han medido e interdatado 13.340 anillos anuales, construyendo una cronología de crecimientos que abarca desde 1818 a 1996. Se han analizado las relaciones entre diversos parámetros dendrométricos medidos y los crecimientos observados, encontrándose en general muy bajas correlaciones. Se han construido tres series medias de crecimiento (cronología media, estandarizada, y en función de la edad) a partir de las cuales se ha analizado la evolución del rodal. Se ha observado un prolongado período de ralentización y estancamiento del crecimiento que se mantiene cerca de ochenta años, seguido de una fuerte corta a la que la masa reacciona con un notable incremento del crecimiento radial en un momento en que la edad media era ya de 101 años.

An adult stand (mean age = 139 years) of Pinus nigra ssp. salzmannii var. pyrenaica has been studied in the W of the Solsonès district (Lleida province, NE of Spain). Cores from 97 adult trees have been bored and measured, obtaining 13.340 annual rings that have been measured and cross-dated, thus building a growth chronology from 1818 to 1996. The relationships between the measured dendrometrical parameters and the observed growth increments have been analysed, finding generally low correlations. Three growth mean series have been built (average chronology, standarized, and age-based), in order to analyse the stand evolution. A long period of growth slowing and supression that lasted for nearly 80 years was followed by a strong cutting and a growth release reaction, when the mean age of the stand was already of 101 years.
