Resumen

Water deficit irrigation to grapevines reduces yield and berry growth altering its ripeningprocess, all of which may influence fruit composition and wine quality. Therefore, the goal ofthis work was analyze variations in fruit composition and specifically, in N-compounds underwater deprivation. The study was carried out using container-grown Tempranillo grapevinesgrown under controlled conditions in a greenhouse. Two irrigation treatments were imposed:a control (well watered), and a sustained deficit irrigation (SDI). Water deficit reduced yield,berry size and concentrations of main phenolic compounds. At harvest, the content of aminoacids and free ammonium was low in both treatments but SDI-treated berries showed asignificant accumulation of amines.
