“…By assimilating respired CO 2 , which is present inside trees at high concentrations (ranging from <1% to over 26% (Teskey et al, 2008)), these photosynthetically active tissues photo-reduce CO 2 similarly as described for green leaves (Pfanz et al, 2002). This re-assimilated CO 2 would otherwise be "lost" to the surrounding atmosphere, which explains why woody tissue photosynthesis is often described within the context of a tree carbon recycling mechanism.…”

“…A further complication may arise if large portions of respired CO 2 are not released to the atmosphere but internally transported between organs as it has been suggested for xylem CO 2 (see Teskey et al, 2008). If a large portion of root respired CO 2 is transported via the xylem water inside the plant and subsequently re-fixed in stem and twigs and/or emitted via the stem to the atmosphere, it would add a further variable source coupled to diel changes in xylem flow delivering depleted δ 13 C res compared to atmospheric δ 13 CO 2 .…”

“…Consequently, stem internal CO 2 concentrations can constantly fluctuate, which in turn can affect the amount of CO 2 diffusing out of the bark (e.g. McGuire and Teskey 2004;Teskey et al 2008;Saveyn et al 2008a, b).…”
