Abstract(s)
Water is increasingly scarce in Mediterranean Europe and irrigated agriculture
is one of the largest and most inefficient users of this natural resource.
Ecological topics such as the “water foot print” have become more relevant for the
academy, consumers, governments and food industry. The wine sector needs solutions
to improve its economical and environmental sustainability. Agronomical solutions,
such as deficit irrigation (water supply below full crop evapotranspiration) have
emerged as a tool for more efficient water use in irrigated viticulture and with likely
positive effects on berry quality. Improving our understanding on the physiological
and molecular basis of grapevine responses to water stress is an important task for
research on irrigated viticulture. Better knowledge of the different genotypic
responses (e.g., leaf gas exchange) to water stress can help to optimize crop/soil
management and improve yield as well as berry quality traits under unfavourable
climate conditions. Mild water deficits have direct and/or indirect (via the light
environment in the cluster zone) effects on berry growth and composition. Another
important challenge is to determine how soil water deficit regulate genes and proteins
of the various metabolic pathways influencing berry composition and consequently
wine quality.
