Coupled Leaf Gas Exchange Model for
Vascular Plants; Modified
for Water Content
Effects with Mosses and Lichens
Fig. 21.1.
Schematic diagram of the model GAS-FLUX. All CO2 respiratory sources are indicated on the
left of the figure,
while all sinks for
CO2 due to photosynthesis are indicated on the
right. Boxes indicate pools while
circles indicate flux rates.
Objective
of the model is to quantify and sum all CO2 fluxes. Net exchange or sum of the sinks and sources is apparent in
the cuvette shown as the difference in CO2 flowing through the measurement system, which provides for model verification.
