Distribution of PPFD absorbed by leaves at different depths of a canopy (A, D, G), relative PPFD (PPFD/PPFD₀) as a function of cumulative LAI (cLAI) (B, E, H) and canopy absorbance as a function of cLAI (C, F, I) on a sunny day during an earlier developmental stage (195 DOY, A, B, C), on a sunny day during a later developmental stage (234 DOY, D, E, F) and on a cloudy day during a later developmental stage (231 DOY, G, H, I). Relative PPFD and canopy absorbance were calculated based on the distribution of PPFD.
