Efecto del fuego sobre la flora micorrícica de una formación natural de carrasca

Abstract

El objetivo de este trabajo es el estudio tanto cuantitativo como cualitativo de los morfotipos de ectomicorrizas que aparecen asociados de forma natural a la carrasca, Quercus ilex L. subsp. ballota (Desf.) Samp. Este estudio se ha llevado a cabo en un carrascal de Navarra afectado en 1993 por un incendio forestal. Los muestreos se han realizado en dos zonas de dicho carrascal, una alterada por el incendio (zona quemada), y otra que no sufrió ninguna perturbación (zona control). Por una parte, se ha analizado el efecto del fuego sobre el estado micorrícico de las carrascas, comparando los porcentajes de micorrización de la zona quemada y de la zona control, y, por otra, se ha contrastado la diversidad y la abundancia de los morfotipos de ectomicorrizas que aparecen en ambas zonas, haciendo una descripción de dichos morfotipos, e identificando al hongo que los forma en la medida de lo posible. SUMMARY The aim of this study is the quantitative and qualitative analysis of the ectomycorrhizal morphotypes naturally associated with evergreen oak, Quercus ilex L. subsp. ballota (Desf.) Samp. The study has been undertaken in an evergreen oak forest located in Navarra. Part of this forest burned in 1993, but most of it remains undisturbed. Thus, samples have been taken from both the burned and the control study sites. The impact of fire on the mycorrhizal state of evergreen oaks has been analysed by comparing the percentages of mycorrhization in the burned and the control areas. On the other hand, the diversity and abundance of the ectomycorrhizal morphotypes occurring in both sites have also been studied. The ectomycorrhizal morphotypes found have been described, and the fungal partner has been identified when possible.
