Photosynthetic rate – A (a), intracellular CO concentration – C (b), transpiration – E (c), stomatal conductance – gs (d), intrinsic 2 i Rubisco A/C i carboxylation efficiency (e) and efficiency of water use – WUE (f) in D. alata seedlings produced under different water regimes (I: Irrigated; II: combined intermittent irrigation without and with 0.75 and 1. Si) in different evaluation periods (T0: zero time; P0: photosynthesis close to zero; REC: recovery: END: end of evaluations). Capital letters compare water regimes within each assessment period (Tukey; p
