Steady-state levels for photosynthetic assimilation rate (A–E), transpiration rate (F–J), and stomatal conductance (K–O) at different levels of incident PFD. Measurements were taken under field conditions for leaves at (bottom to top) 1-m (n = 53), 1.5-m (n = 59), 2-m (n = 91), 2.5-m (n = 64), and 3-m (n = 84) height.
