Grape berry mineral composition in relation to vine water status and leaf area/fruit ratio

Résumé

Aim : The results presented in this review come from an original study on the accumulation of potassium, calcium, magnesium and sodium in berries on vines submitted to different water status treatments. This study was carried out during the 2006 season on young (4 year old) vines of Grenache Noir (clone 134) grafted onto Richter 110 grown on clay limestone soil (dry Mediterranean limestone marl) at the Pech Rouge experimental vineyard at INRA-Gruissan, France. The vineyard was planted with a north-south row orientation, 1 m (vine spacing) x 3 m (row spacing), trained according to the lyre trellis system, pruned in single cordon of Royat and watered by a drip irrigation system. Two levels of water status, irrigated (I) and non-irrigated (NI) were investigated. For each level of water status, two levels of total leaf area were compared: uniform growth of primary shoots was obtained by topping at 10 primary leaves or 18 primary leaves and by removal of secondary shoots (side shoots) and tendrils from berry-set onwards. Second 3 level bunches were removed to leave only one bunch per shoot. To implement the two water level treatments, irrigation commenced from bunch closure onwards
