Some years, climate conditions and biological events increment the fertility of vines, which can lead to over cropping and a decrease of wine quality.

Under the context of global change, any decrease in water use by crops is essential, because water is becoming a more and more scarce resource, especially in Mediterranean areas, where grapevines are grown.

In the globalization conditions possible future scenarios, optimistic and pessimistic are supposed.

In this work the salient results of the viticultural and ecomomic researches earned out on interesting italic varieties of Latium (Malvasia of the Lazio and Cesanese d’Affile) and an international vsriety (Cabernet sauvignon), “Cordon Spur of Conegliano” (CSC) as growing system, will be exposed.

The uptake of nitrogen and other nutrients by grapevine rootstocks may differ according to the size of the root system and timing of fine root growth flushes during the season.

Some water fluxes are simulated in Ecotron: 2 general levels of water limitation combined with 3 modalities of quick, severe and temporary water deficit occurring at beginning of ‘veraison’, or after at mid- maturation.

Stomatal conductance (g,), net photosynthesis (AN) and leaf water potential (Ψleaf) in 5 grapevine cultivars were measured in July, August and September 2008.

Intercropping vineyards with cover crop is a practice currently developing in wine production areas.

In North-Eastern Italy water demand for vineyards irrigation is constantly increasing, but this conflicts with the high civil and industrial rates of water consumptions in the area, which is one of the most densely populated in Europe.

This study demonstrated that remote sensing using high definition multispectral airborne imaging can be used to identify useful differences within a vineyard.

While tremendous advances have occurred in spatial climate data products, no large-scale update to our understanding of climate-viticulture structure and suitability for the western US has be done in the last three decades.

The aim of our study is to evaluate the effects of a total grass cover practice (between and under the rows of vine) in vineyards on grapevine production and on quality in order to develop soil management practices without using herbicides.

The vine growth integrates a global behaviour related to the water and nitrogen consumption of the plants.

Canopy architecture can derive from a primary basic form and be achieved by secondary interventions, that allows at first to use classical or simple technics and then to adapt some modalities (Carbonneau, 2007), either on the trellis or on the canopy, to the reality of the vine architecture.

The major focus of our research is to explain terroir effects that impact wine varietal character. We sought to elucidate potential determinants of terroir by choosing vine water status as a major factor of the terroir effect.

Croatina and Pinot noir vineyards at three different elevation (80, 180 280 m asl) were compared in Oltrepò Pavese (northern Italy).

V. vinifera L. cv Merlot clone R3 grafted on the hybrid V. riparia x V. rupestris 3309 C rootstock was grown on pots containing calcareous or non calcareous soil.

This study examined the structure and trends of climate parameters important to winegrape production in the Penedes, Priorat, and Segrià regions of NE Spain, during 1952-2006.
