Changes in relative QA reduction (qL) (A,C) and PSI oxidation ratio [Y(ND)] (B,D) during exposure to 4°C and 300 μmol photons m-2 s-1. After measuring qL and Y(ND) at 24°C and 297 μmol photons -2 s-1, leaves were incubated in the presence or absence of lincomycin (1 mM) overnight in darkness and subsequently exposed to 4°C and 300 μmol photons m-2 s-1 for 2, 4, or 6 h. During chilling-light treatment, qL and Y(ND) were measured at 4°C and 297 μmol photons m-2 s-1. Values are means ± SE (n = 6).
