and the amount to reduce the intensity (P2_Ramp
Dept).
The Phase2 F data is regressed vs. 1E4/Q using only
Phase 2 data. The resulting slope is captured and the
intercept is logged to
Fm' .
Values that are captured or calculated and logged during
an MPF only are:
l
P1_dur : Phase 1 Duration (msec)
l
P2_dur : Phase 2 Duration (msec)
l
P3_dur : Phase 3 Duration (msec)
l
P1_FMax : Max F during Phase 1
l
P2_slp : Slope of F vs 1/Q during Phase 2
l
P3_Fmax : Measured Fmax during Phase 3
l
P3_Pred : Predicted Phase 3 F using Phase 2 regression
l
P3_DeltaF : Difference between measured and pre-
dicted Phase 3 F ( P3_Fmax - P3_Pred )
Additional fluorometer calculations
Electron Transport Rate (ETR) is also calculated from all
light-adapted flashes from
9-47
where
φ
PSII comes from the flash as shown above, Q
amb
is from the ambient PAR sensor (equation 9-20), abs and
PS2/1 are constants given by the user in the con-
figuration.
Logged Variables
The LI-600 logs variables into two groups: porometry
and fluorometry.
