Electron fluxes through PSII in response to measurement irradiance calculated in two different ways in leaf discs of control (a) and shade-grown (c) Zea mays (NADP-ME) and control (b) and shade-grown (d) Panicum bisulcatum (C3 grass). LEFO2 (the gross oxygen evolution rate multiplied by four) represents the linear electron flux through both photosystems; ETR2 is the measure of electron flux through PSII based on Chl fluorescence emitted from a certain depth in leaf tissue calculated using experimentally derived fII. Measurements were taken under the temperature of 28 °C and high pCO2 condition (4%). Values are mean ± S.E. (n = 4 leaf discs)
