![Relationships of (Jc + Ja)/PAD versus ƊF/Fm at 2% (solid lines) and 21% O2 (dashed lines) for normal and mutant maize. See Figure 5 for definition of symbols. Note the high fidelity of the first- and second-order polynomial regression fits (R 2 = coefficient of determination) to the mean data points and the relatively larger separation between the fits for mutant compared to normal leaves. These fits enable empirical estimation of P diss in 21% O2 by referring the associated ƊF/Fm to the regression equations to evaluate [(Jc + Ja)/PAD]2 and [(Jc + Ja)/PAD]21 (Eq. 3).
