3). 1. The initial slope of the curve is the quantum yield (mol CO2 taken up per mol photon of PFD absorbed), which strongly depends on the functioning of the photosystems. 05 mol CO2 per mol photon for many species under optimal natural conditions (Ehleringer and Björkman, 1977). The quantum requirement of leaves is the inverse of the quantum yield and is about 20 photon per molecule of CO2 taken up. Quantum requirements as low as 14 have been achieved by subjecting plants to low temperatures and either low [O2] or high [CO2] (Ehleringer and Björkman, 1977).
Also, it is risky to extrapolate with empirical models of this type and attempt to predict values much outside the range of values used in developing the model. 1). Extrapolation is particularly dangerous when using empirical models based on polynomial equations. 1. 1 Moisture content of cowpea seed, on a fresh weight basis, that have been equilibrated with atmospheres having constant relative humidities at room temperature. 1).

Photons at a wavelength between 400 and 700 nm have the levels of energy per photon required for eliciting the photochemical reactions of photosynthesis and are described as photosynthetically active radiation (PAR).
