Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]

open access: yes, 2013
Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...
