Effets combinés de l'augmentation de la concentration atmosphérique en CO2 et du niveau de fertilisation azotée sur la gestion du carbone et de l'azote chez le chêne pédonculé (Quercus robur) et le hêtre (Fagus sylvatica)

Abstract : This work addresses the impacts of elevated atmospheric [CO2] on forest productivity. We considered the interactive effects of elevated [CO2] and N fertilization level on both C and N metabolism. Our results underline the importance of N availability in controlling the response of Quercus robur to elevated [CO2], and in particular during spring growth by the way of its major effect on C storage compounds, and primarily on N storage compounds. In response to elevated [CO2], we found that wood density was increased for Quercus robur but not for Fagus sylvatica. We also found an opposite time course of the growth responses in these two species.
