The objective of this study was to characterize the photosynthetic behavior of grapevines in protected cultivation with different volumes of water available. The experiment was conducted in Vale dos Vinhedos, Brazil with covered plants of ?Italia?, sustained on a discontinued pergola trellis system. The treatments consisted different available water capacity (AWC) in the soil. The control treatment (CT) was maintained at field capacity with a minimum water potential limit (ψm) of -33.34 kPa (100% AWC). The minimum limit of the ψm was -42.12 kPa (83% AWC) at T1, -76.28 kPa (53% AWC) in T2 and -94.32 kPa (30% AWC) at T3. The liquid assimilation of CO2 (A, μmol CO2 m-2 s-1) in response to the flow density of the photosynthetically active photons (μmol m-2 s-1), were determined using a gas analyzer. When compared with the CT, the (Amax) values in T2 were 27,48% and 33% less and in T3 37,92% and 46,5% less, respectively in 2009/10 and 2010/11, while T1 didn?t differ from the control. Water restrictions in covered grapevines had an influence on the foliar photosynthetic potential, with the limit of 83% AWC the most suitable condition considering the economy of water and the maintenance of foliar function. |
