Effects of Mn-excess on OJIP transients (A and B), and the different expressions of relative variable fluorescence derived from the average OJIP transients: (C) between Fo and Fm: Vt= (Ft -- Fo)/(Fm -- Fo) and the differences of the two samples to the control sample (ΔVt); (D) between Fo and F300 μs: WK = (Ft -- Fo)/(F300 μs-- Fo) and the differences of the two samples to the control sample (ΔWK) and (E) IP phase: (Ft -- Fo)/(FI -- Fo) -- 1 = (Ft -- FI)/(FI -- Fo) in dark-adapted sour pummelo leaves.
