Grapevines of the variety Vitis vinifera L. cv. Pinot Noir (clone 9-18, grafted onto 5BB) were subjected to different water regimes (irrigation treatments) over the growing season. Physiological indicators were used to monitor the plant water status (leaf and stem water potentials and relative carbon isotope composition (d13C) in must sugars). Lea...
