Table 2 Formula for calculating dynamic parameters of rapid chlorophyll fluorescence induction.
Parameter and formula | Explanation of the parameters |
|---|---|
VJ=(Fj-Fo)/(Fm-Fo) | Relative variable fluorescence at point J |
VI=(Fi-Fo)/(Fm-Fo) | Relative variable fluorescence at point I |
PI(ABS) = RC/ABS[φPo/(1-φPo)][ψo/(1- ψo )] | Performance index mainly based on absorbing light energy |
ABS/CSm ≈ Fm | Light energy absorbed per unit area (at t = Fm) |
TRo/CSm = φPo·(ABS/CSm) | Light energy captured per unit area (at t = Fm) |
ETo/CSm = ΨEo·(ABS/CSm) | Quantum yield of electron transfer per unit area (at t = Fm) |
DIo/CSm=(ABS/CS)-(TRo/CSm) | Heat dissipation per unit area (at t = Fm) |
ABS/RC = Mo·(1/VJ)·(1/φPo) | The light energy absorbed by the unit reaction center |
TRo/RC = Mo·(1/VJ) | The energy captured by the unit reaction center for reducing QA |
ETo/RC = Mo·(1/VJ)·ψo | Energy captured by unit reaction center for electron transfer |
DIo/RC=(ABS/RC)-(TRo/RC) | Energy dissipated by unit reaction center (at t = Fm) |
