Response of grapevine cv. ‘Brancellao’ and ‘Sousón’ to supplementary irrigation: Water relations, vine growth, yield and berry and wine composition

Abstract: SUMMARYGrowers are concerned about the negative impacts on vine yield and berry quality caused by global warming. Irrigation systems are increasingly being installed in vineyards in order to counteract those problems. Therefore, an efficient irrigation management is required. In this context, a field experiment was carried out over three years (2012)(2013)(2014) on red Vitis vinifera (L.) cv. 'Brancellao' and 'Sousón' in order to assess the effects of supplementary irrigation on vine performance and must and w… Show more

“…A midday Ψ s of ≤1.4 MPa has clearly detrimental effects on photosynthesis, quality and yield. Some authors report that over optimal irrigation can have a detrimental effect on sugar content and lead to delayed ripening, increased acidity, reduced berry colour intensity and a smaller yield [35, [79][80][81], but in some of these experiments, however, midday Ψ s was kept at above −0.9 MPa [80].…”
