“…In summary, yield was significantly increased and berry composition was affected (more acidic and lower soluble solids content) when using irrigation. Under the water scarcity scenario that the world is facing, our results indicated that irrigation in Albariño vineyards from a humid region is not necessary and, likely, not sustainable, confirming previous results obtained for other white cultivars (Trigo-Córdoba et al, 2015). However, studies with other irrigation periods and amounts in other areas of Galicia may produce different results , as observed for other white varieties in coolhumid (Reynolds et al, 2007) and Mediterranean climates (Basile et al, 2012).…”

Aims: Vine-growers worldwide are concerned about climate change effects on grape yield and quality. Drip irrigation systems are increasingly being installed even in humid regions such as Galicia (NW Spain). In this context, a field experiment was carried out over three seasons (2012)(2013)(2014) on white Vitis vinifera L. cv. 'Albariño' to assess the effects of deficit irrigation on vine physiology, yield and must and wine composition. Methods and results:Rain-fed vines were compared with a treatment irrigated to 50% of the estimated crop evapotranspiration (ET c ) from bloom to two weeks before harvest. Irrigated vines showed more positive stem water potentials than those rain-fed. Yield was unaffected by irrigation except in 2014 (19% increase). Pruning weight was increased by irrigation. Must soluble solids tended to decrease and total acidity to increase with irrigation; however, wines were similar between treatments. Water productivity was slightly higher under rain-fed conditions. Conclusion:Under the conditions of this experiment, irrigation was of no interest either in terms of grape and wine quality or in terms of net income.Significance and impact of the study: These results may be useful for managing water resources in vineyards under similar climatic conditions. Key words: Drip irrigation, crop yield and quality, vine water status, water productivity, white wine Abstract manuscript

SUMMARYAmino acids constitute a source for yeast metabolism and, thus are of paramount importance to wine flavour and aroma. Their concentrations in must depend greatly on grape variety. The aim of this work was to describe the amino acids profile of two white grapevine varieties: 'Godello' and 'Treixadura', produced in Galicia (NW Spain). The study was carried out over two consecutive vintages (2012 and 2013). Amino acids profiles of the musts were determined using HPLC. Although the musts from the two varieties presented common major and minor amino acids, the greatest contents were observed for 'Treixadura'. 'Godello' and 'Treixadura' varieties were arginine-accumulators, since this was the amino acid found at the highest level in the musts from the two cultivars. Amino acids contents were higher in 2012 than in 2013, likely due to climate differences between years. RESUMOOs aminoácidos constituem uma fonte para o metabolismo das leveduras e são de suma importância para o sabor e o aroma do vinho. As suas concentrações no mosto dependem grandemente da variedade de videira. O objetivo deste trabalho foi descrever o perfil de aminoácidos de duas variedades brancas de videira: 'Godello' e 'Treixadura', produzidas na Galiza (Noroeste de Espanha). O estudo foi realizado em duas vindimas consecutivas (2012 e 2013). Os perfis de aminoácidos dos mostos foram determinados utilizando HPLC. Os mostos das duas variedades apresentaram maiores e menores aminoácidos comuns, sendo observadas maiores concentrações na 'Treixadura'. No mosto das variedades 'Godello' e 'Treixadura' o aminoácido predominante foi a arginina. As concentrações de aminoácidos foram maiores em 2012 do que em 2013, provavelmente devido a diferenças climáticas entre anos.
