Abstract:
... KEY MESSAGE : Efflux-based estimates of stem respiration in oak trees during the dormant season were biased by axial diffusion of locally respired CO ₂ . Light-induced axial CO ₂ diffusion along the stem due to woody tissue photosynthesis may lead to equivocal estimates of stem respiratory coefficients during the dormant season, which are generally used to estimate maintenance respiration througho ...
