Table V. Simulated Kox and its components.
Values of Kox and its components, Kb and Kob, simulated under default values for all parameters as given in Tables III and IV (left three columns of results) are shown. Simulated Kox values for three additional scenarios involving unknown parameters are shown in the right three columns of results: the presence/absence of a Casparian strip in the BS (Casp), specification of cell wall thicknesses in the model at 20% or 100% of values measured by LM (ρta = 0.2 or 1), and specification of horizontal palisade cell connectivity (contact fraction) at 0% or 100% of values measured by LM (ρfcph = 0 or 1). Means ± se values and medians ± median absolute deviations are shown at bottom. Units are mmol m−2 s−1 MPa−1.
