Obtainable parameters
Fo minimum initial fluorescence, also known as basal fluorescence or dark fluorescence. The chlorophyll (Chl) fluorescence emission intensity when the photosystem II (PSII) reaction center of the photosynthetic system is fully open after sufficient dark adaptation.
Fm maximum fluorescence. The Chl fluorescence emission intensity when the PSII reaction center of the photosynthetic mechanism is completely closed after sufficient dark adaptation.
The minimum fluorescence under Fo 'light. The fluorescence emission intensity of chlorophyll (Chl) when the photosystem II (PSII) reaction center of a fully adapted photosynthetic system is fully open. The formula for calculating Fo 'is Fo'=Fo/(Fv/Fm+Fo/Fm ')
Maximum fluorescence under Fm 'light. The Chl fluorescence emission intensity when the PSII reaction center of the photosynthetic mechanism is completely closed after sufficient light adaptation.
F 'steady-state fluorescence (i.e. Fs)
Fq 'is Fm' - F '
XE （Fv／Fm）
Potential excitation energy capture efficiency of PSII reaction center.
XE (Fv’／Fm’）
The excitation energy capture efficiency of PSII reaction centers that are open under light.
EF (Fq '/Fv')
OE (Fq’/ Fm’)
The actual photochemical quantum efficiency of PSII in the presence of reactive light, i.e. the actual quantum efficiency of charge separation in PSII reaction centers, reflects the proportion of excitation energy used in the photochemical pathway to the total excitation energy entering PSII, which is an important indicator of plant photosynthetic capacity.
NPQ non photochemical quenching coefficient. Reflects changes in the ability of plants to dissipate heat.
QN non photochemical quenching coefficient
Qp photochemical quenching coefficient. It reflects the degree of openness in the PSII reaction center, while 1-qP reflects the degree of closure in the reaction center and the degree of reduction in QA.
ETR electron transfer rate (can be calculated by oneself). ETR = PPFD × OE(Fq’/ Fm’)× 0.84 ×0.5
