Measurement of Chl fluorescence using the FLD method under solar light and saturation pulse for estimating ΦPSII of paprika leaf. (A) Temporal changes in leaf radiant intensity spectra measured using a HR2000+ spectrometer under solar light (1450 μmol m−2 s−1), where SLRL is the saturation light pulse (4450 μmol m−2 s−1) using red laser (660nm) and SLPAM is the saturation light pulse (blue LED, about 10 000 μmol m−2 s−1) of JUNIOR PAM. The solid line is the spectra of 758.9nm and the dotted line is that of 760.4nm. A mean value of 0.4nm wavelength width (W) was used. (B) Temporal changes in Chl fluorescence intensity (F760.4) calculated by the FLD method. (C) Temporal changes in Chl fluorescence yield (ΦF760.4). The dotted line is the changes in ΦF760.4 and the solid line is the value after median filtering during the 10 s before the SLRL illumination for estimating ΦPSII.
