[automatically translated] In Sicily, it characterized by warm and little rainy summers irrigation and interventions in green are of great importance in the definition of the production results and quality of the vineyard. It was therefore conducted a study comparing two different clayey soils, plants defoliated all'allegagione with no defoliated plants in dry conditions and irrigation system plan managed, the latter, with the pre-dawn leaf water potential. An analysis of vegetative-production plant and quality of the grapes were no significant differences between treatments, including irrigation schemes and in some cases also showed an interaction effect. Early defoliation resulted in an increase of the vegetative activity, improved the framework grape polyphenols and has delayed the acidity degradation.
