Evaluate the Kubelka–Munk theory for predicting both reflectance and transmittance of light through stacked leaves and extend the model to field plant canopies.
Measured light reflectance and transmittance across stacked mature cotton leaves over a spectral range of 0.5–2.5 μm using a laboratory spectrophotometer.
Formulated a canopy extension using regression analysis of internal light flux measurements and derived differential coefficients for stacked-leaf and field canopy systems.
Demonstrated that the two-parameter Kubelka–Munk formulation accurately predicts both reflectance and transmittance, outperforming the single-parameter Beer's law.
Achieved a standard deviation of approximately 1% between theoretical predictions and experimental measurements after calculating and removing systematic biases.
