Saturation Pulse Analysis

Measured: Ft, Fo, Fm, F, Fo' (also calculated), Fm'. Fast polyphasic rise and decay kinetics (time resolution up to 10 μs). PAR using Spherical Micro Quantum Sensor US-SQS/WB or Mini Quantum Sensor US-MQS/WB.

Calculated: Fo' (also measured), Fv/Fm and Y(II) (maximum and effective photochemical yield of PS II, respectively), qL, qP, qN, NPQ, Y(NPQ), Y(NO) and ETR (electron transport rate), C/Fo (constant fraction of Fo not constituting PS II chlorophyll fluorescence)


Fitting Routines

Fitting routine for fast fluorescence rise from 0 to the I1 level to determine functional absorption cross-section of PS II and PS II-specific electron transport rates. Fitting of fluorescence decay after light-to-dark transition by up to three exponentials to estimate primary electron transfer rates. Fitting routine for determination of the cardinal points α, Ik and ETRmax of light curves.
