Key Concepts for Measurement
Fluorometer Calculated Endpoints - Maximum efficiency of PSII
(Fm0-F0)/Fm0 = Fv/Fm0 = ΦPSII/qP
This is a measure of the quantum efficiency of PSII if all reaction centers are open
Variables Measured Directly
- F0- yield of fluorescence in the absence of photosynthetic light
- Fm0 - maximum fluorescence; obtained in the absence of photochemical quenching
