Evaluation of the incidence of severe trimming on grapevine (Vitis vinifera L.) water consumption

摘要: Abstract Viticulture in Southern Europe heads towards a scenario of drier and warmer the growing seasons due to climate change. This decrease amount water available for vines increase evapotranspiration make necessary finding strategies reduce vineyard needs. In this context, effect severe trimming (40–60% shoot length), performed at pea-size stage, on plant status was evaluated four different vineyards located North Spain. Severe improved clearly only when conditions were more demanding, whereas slight improvement or no change observed elsewhere. Lower leaf areas resulted less deficit following logarithmical trend revealing that pronounced low area levels. had non-significant effects cluster number, yield weight, but presents tendency total soluble solids content acidity, consequently delaying ripening.
