Drought effects on buds growth and dynamic of Tunisian cork oak populations Ennajah, A. Azri, W. Sai Kachout, S. Taibi, K. /Mouillot, Florent Ourcival, J.M. FORET SECHERESSE DYNAMIQUE DE POPULATION PHENOLOGIE DEFICIT HYDRIQUE BOURGEON CROISSANCE ETUDE REGIONALE ETUDE COMPARATIVE CHANGEMENT CLIMATIQUE Forest species have adapted to their local climate by changing some of their phenological characteristics. Differential phenological responses may modify tree chance of survival by altering the competitive balance between them. The study of key phenological stages (budding, budburst, flowering, falling leaves ...) knew a renewed interest these last years for climate changes consequences researches. Characterizing the phenological variability response, of five Tunisian cork oak populations from contrasting climatic situations, in front to water deficit, has been the subject of this study. Large differences between populations from highest and coldest sites as well as those of lowest and warm sites were detected and adaptative responses specific to some populations were founded. 2013 text https://www.documentation.ird.fr/hor/fdi:010062175 fdi:010062175 Ennajah A., Azri W., Sai Kachout S., Taibi K., Mouillot Florent, Ourcival J.M..
