Pearson correlation (R) of all measured dynamic and steady-state (filled tiangles) photosynthetic traits measured in rice flag leaves. Negative correlations are in blue, positive correlations are in red. Traits at steady-state are: intrinsic water-use efficiency (iWUE=A/g_s), transpiration (E), intercellular CO₂ concentration (C_i), stomatal conductance (g_s), and net CO₂ assimilation in saturating light (A_sat). Traits at non-steady state over the first 300 s of induction are: the time at which A reached 50% and 90% of A₃₀₀ (IT₅₀ and IT₉₀, respectively), average C_i during first 300 s of induction (C_{i avg}), average intrinsic water use efficiency (iWUE_avg=Ā₃₀₀/g_{s avg}), average g_s, the maximum A during induction (A_Max), A at the end of this period (A₃₀₀), and the average A (Ā₃₀₀). A significant R value is marked by a black line on the scale (0.8).
