Fig. 3. Leaf net assimilation (A) and stomatal conductance (g) measured at a photosynthetic photon flux density (PFD) of 1500 µmoles (photons) m^–2 s^–1 vs. leaf temperature (T_L) for the 7.5 mm irrigation amount treatment in 2005. Numbers in parentheses are the number of days since the last irrigation or significant rainfall.
