| Method |
"To transform
all values into g C, the molar masses of C and CO2 were
applied (12 and 44 g/mol, respectively), and a molar mass of
30 g/mol was used as a general form of carbohydrate (CH2O).
Therefore, measurements of CO2 fluxes were multiplied by the
molar ratio 12/44, and dry biomass values were multiplied by the
molar ratio 12/30." |
| Comments |
"Previous studies of the C balance at the tree scale have shown a
different flux partitioning than here, with growth estimated as the major flux (Table 3)...The partitioning of C fluxes into the tree’s compartments
(Fig. 5) can be also compared with the results of earlier studies
(Table 3), with some degree of uncertainty. The annual C uptake
calculated for 25-yr-old F. excelsior (primary source [3]) was relatively
close to the value estimated here. Results from that study
and from Agren et al. (primary source [1]) were also in agreement with the
major role of roots in the tree’s respiration flux." See notes beneath table |
