Table 2.

Maximum quantum efficiency of PSII (Fv/Fm), relative PSII operating efficiency (ΦPSII), coefficient of photochemical quenching (qp), the quantum yield of non-light-induced nonphotochemical quenching (ΦNPQ), the quantum yield of light-induced nonphotochemical quenching (ΦNO), and the fraction of oxidized plastoquinone (q_L) calculated using measurements under saturating (1000 µmol photons m⁻² s⁻¹) 90% red, 10% blue light. Different letters indicate significant differences (p ≤ 0.05; n = 3 or 4).
