Dynamics of physiological parameters. Changes in leaf water potential (a), maximum net photosynthesis (b), stomatal conductance (c), intrinsic water use efficiency (d), Area parameter (e) and ABA content (f) for Sangiovese and Montepulciano vines under well-watered (WW) and water-stressed (WS) conditions. Data were taken 2, 6 and 27 days after WS. For each measurement date, the means ± SE followed by different letters are significantly different at p < 0.05 according to the Student-Newman-Keuls test
