Net photosynthesis markedly dropped in NI plants (from10 to 1.8 mol m−2s−1) and these low values remained stable until the day of maximum stress (14 DAT). The gs diminished from 0.42 to 0 mol H2O m−2s−1and E varied between 4 and0.06 mmol H2O m−2s−1. NI plants demonstrated a partial recovery after being irrigated with the same amount of water as FI (14days after the beginning of the water stress). That is, 48 h after re-watering, in NI treatment, An values were a 54% of the initial value and 72 h after re-watering, these values rose to 72% of the initially value, a level that remained constant until the end of the trial.
