图3 强闪光处理对棉花叶片PSI氧化还原状态的影响 A: 光下PSI量子产量(ΦPSI); B: 光下PSI被氧化的比例(ΦND), 是PSI由于供体侧限制引起的PSI非光化学量子产量; C: 光下PSI未发生氧化的比例(ΦNA), 是由于受体侧限制引起的PSI非光化学量子产量。

Fig. 3 Effects of repetitive intense flashes on the redox state of P700 in cotton leaves A: effective photochemical quantum yield of PSI (ΦPSI); B: fraction of overall P700 that is oxidized in a given state (ΦND), i.e. the quantum yield of non-photochemical energy dissipation due to donor side limitation; C: fraction of overall P700 that cannot be oxidized in a given state due to reduced PSI electron acceptors (ΦNA), i.e. the quantum yield of non-photochemical energy dissipation due to acceptor side limitation.
