Fluorescence parameters | Explanation |
---|---|
Vt = (Ft − Fo)/(Fm − Fo) | Relative variable fluorescence at time t |
WOJ = (Ft − Fo)/(FJ − Fo) | Ratio of variable fluorescence Ft − FO to the amplitude FJ − FO |
WOK = (Ft − Fo)/(FK − Fo) | Ratio of variable fluorescence Ft − FO to the amplitude FK − FO |
PItotal | Performance index for the conservation of energy from photons absorbed by the PS II antenna to the reduction of PSI acceptors |
φEo | Quantum yield of the electron transport flux from QA to QB |
Fv/Fm | Maximum quantum yield of primary photochemistry |
φRo | Quantum yield of the electron transport flux until the PSI electron acceptors |
δRo | Efficiency with which an electron from QB is transferred until PSI acceptors |
ψRo | Electron transport efficiency except QA |
ψEo | Electron transport efficiency from QA− to the PSI electron end acceptors |
OEC activity | oxygen-evolving complex activity; OEC centers = [1 − (VK/VJ)] treatment / [1 − (VK/VJ)] control |
