For this purpose, the process of wood formation (xylogenesis) and leaf phenology were monitored during two years at 14 sites of natural forests (nive for Quercus robur, and five for Q. pyrenaica). A retrospective (dendrochronological) study of tree rings and anatomical variables (earlywood vessels) was also carried out at four out of the 14 sites. Climate-growth relationships at the 14 sites were analyzed, the synchronicity between wood growth and leaf development was described, and the water content of crown organs (branches, buds, leaves) was quantified to minimize observer’s subjectivity for leaf phenology.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/XilogénesisFenología foliarAnillos de crecimientoMaterias::Investigación::24 Ciencias de la vida::2417 Biología vegetal (botánica)::241711 Anatomía vegetalMaterias::Investigación::24 Ciencias de la vida::2417 Biología vegetal (botánica)::241713 Ecología vegetaldoctoral thesisopen access
