Fast fluorescence induction parameters

Fast fluorescence induction parameters of curves in Figure 3. Leaf discs were incubated for 2 h under 150 μmol m−2 s−1 white light in distilled water (control), 1 mm GSNO, and 1 mm GSNO + 4 mg mL−1 Hb, then dark adapted for 15 min. Following this treatment, chlorophyll fluorescence of leaf discs was induced by 3 s of 130 μmol m−2 s−1 red light. The F0, FI-F0, and FP-F0 parameters are shown in arbitrary units. Values represent means ± sd (n = 5).

Control 258.3 ± 4.6 46.3 ± 7.6 727.0 ± 6.0 1.1 ± 0.01
GSNO 270 ± 6.1 88.0 ± 6.9 309.3 ± 13.3 0.3 ± 0.04
