Stomatal conductance (gsw) over a range of field capacities (FC), VPDleaf, and light. (A) 82% FC (n = 112). (B) 86% FC (n = 96). (C) 90% FC (n = 112). (D) 95% FC (n = 96). All axes are scaled the same, with the x-axis showing VPDleaf, the y-axis Qamb, and the z-axis gsw. The color scale for all is scaled the same. Red represents a high gsw of ∼4, while orange is ∼3, green is ∼2, and blue is ≤1 µmol H2O m−2·s−1.
