Fig. 4 Leaf gas exchange of plants subjected to control (•), shade () and water deficit () treatments during pre-pollination (upper panels) or post-pollination (lower panels) developmental stages in Exp. II. Net photosynthetic CO₂ exchange rate (P_n; left panels) and stomatal CO₂ conductance (g_s; right panels) of 3 to 5 replicates (mean ± SEM) are shown. Data are plotted with respect to the days from treatment termination (DFTT). On the days of treatment termination (0 DFTT), plants were re-watered or removed from shade at 0800 and gas exchange data was acquired at 1100 to 1400 h.
