Vegetative and Reproductive Behaviour of Vitis vinifera L. (cv. ‘Cabernet Sauvignon’) Vines Growing Under Non-Irrigated Conditions and Moderate Water Stress Induced by Different Irrigation Systems

An experiment was carried out to evaluate the effect of different levels of water stress and different irrigation systems to the vegetative and reproductive behaviour of Cabernet Sauvignon ines/140Ru, vertically trained, during the growing season 2003-2004. The vineyard was located in Sicily (in the south of Italy); the soil was loamy-sand and the climate semi-arid. Were compared five treatments: four treatments irrigated, maintaining a moderate water stress level, by drip irrigation (T1) and sub-irrigation (T2, T3 and T4) and one treatment non-irrigated (T5). The sub-irrigation treatments were different by the number and the distance of the water tubes by the rows of vines. The results sho…

22. VEGETATIVE AND PRODUCTIVE BEHAVIOUR IN VITIS VINIFERA L.(CV. CABERNET SAUVIGNON) UNDER NON IRRIGATED VINES AND MODERATE WATER STRESS LEVEL IN DIFFERENT IRRIGATION SYSTEMS

Response of grapevine (Cabernet Sauvignon cv) to above ground and subsurface drip irrigation under arid conditions

Abstract The response of wine grapes to irrigation systems was investigated in a Cabernet Sauvignon/140 Ru vineyard in sandy loam soil in Sicily during a two-year study. Two different drip irrigation systems were evaluated: one surface drip and two subsurface drip irrigation systems, with the trickle line located at different distances from vine trunks. Vegetative and quantitative parameters, must quality and root distribution were compared among irrigation treatments. During the two study years, irrigation of grapevines via a subsurface drip system resulted in greater water use efficiency without affecting must composition. Establishing the trickle line near the trunk positively influenced…
