[en] Long-term damages caused by fungi on tree radial-growth and its interaction with climate have been little studied. The incidence and the severity of damage caused by the pathogenic fungus Melampsorella caryophyllacearum on Abies alba in three plots sampled in the Irati forest (Western Pyrenees, Navarra) were quantified. The radial growth of 15 symptomatic trees and 15 asymptomatic trees using dendrochronological techniques were compared. The relationships between monthly climatic data (mean maximum temperature, precipitation) and radial growth of symptomatic and asymptomatic trees were established to determine the different responses of growth to climate between both types of individuals. Radial growth was significantly lower in symptomatic than in asymptomatic trees since the 1980's when a higher frequency of traumatic resin ducts was detected. Different response functions according to the symptomatology of trees were not observed. The radial growth of A. alba was positively correlated to November mean maximum temperatures of the year prior to growth, and to February and April mean maximum temperatures of the year of growth. Negative relationships between growth and higher September mean maximum temperatures during the year before the tree-ring was formed, and with March and August mean maximum temperatures during the year of tree-ring formation were found. Finally, the radial growth of A. alba was also positively correlated to July precipitation during the year of growth.

[es] Los da&ntilde;os causados a largo plazo por hongos sobre el crecimiento radial de los &aacute;rboles y su interacci&oacute;n con el clima han sido poco estudiados. Se cuantific&oacute; la incidencia y la gravedad de los da&ntilde;os causados por el hongo pat&oacute;geno Melampsorella caryophyllacearum sobre Abies alba en tres parcelas en el bosque de Irati (Pirineos occidentales, Navarra). Mediante t&eacute;cnicas dendrocronol&oacute;gicas se compar&oacute; el crecimiento radial de 15 &aacute;rboles sintom&aacute;ticos frente a 15 asintom&aacute;ticos. Se relacionaron los datos clim&aacute;ticos mensuales (temperatura media de las m&aacute;ximas, precipitaci&oacute;n) y el crecimiento radial de &aacute;rboles sintom&aacute;ticos y asintom&aacute;ticos para determinar si exist&iacute;an distintas respuestas frente al clima entre ambos tipos de individuos. El crecimiento fue significativamente menor en los &aacute;rboles sintom&aacute;ticos a partir de los a&ntilde;os 80, cuando se detect&oacute; una mayor frecuencia de conductos resin&iacute;feros traum&aacute;ticos. No se encontraron diferencias en las funciones respuesta seg&uacute;n la sintomatolog&iacute;a de los &aacute;rboles. El crecimiento radial de A. alba estuvo positivamente correlacionado con las temperaturas medias de las m&aacute;ximas de noviembre del a&ntilde;o previo, y febrero y abril del a&ntilde;o de crecimiento. Se encontraron relaciones negativas del crecimiento ante elevadas temperaturas medias de las m&aacute;ximas durante el mes de septiembre previo a la formaci&oacute;n del anillo, y durante los meses de marzo y agosto del a&ntilde;o de formaci&oacute;n del anillo. Finalmente, el crecimiento radial de A. alba tambi&eacute;n estuvo positivamente correlacionado con una elevada precipitaci&oacute;n en julio del a&ntilde;o de crecimiento.
