【 摘 要 】

The results showed that moderately irrigated vines produced berries with a higher anthocyanin content (expressed as mg/100 berries) than non-irrigated vines. These findings suggest that moderate levels of water doses may actually improve the physiological status of vines grown in very dry areas, resulting in higher yields and higher quality grapes. The higher yields were mainly related to larger berry size which led to a lower anthocyanin content when expressed as mg/kg, due to a dilution effect. This fact is also responsible for the lower anthocyanin content of the wines elaborated with grapes from irrigated vines although irrigation per se did not decrease the concentration of anthocyanins in grapes.
