Επίδραση της τροποποίησης του χειμερινού κλαδέματος και θερινών κλαδεμάτων σε αμπέλια ποικιλίας Ασύρτικο στην απόδοση και στη σύνθεση σταφυλιών και οίνου.

Abstract

Climate change accelerates the ripening season of the vines significantly affecting the quality characteristics of the grapes and the wine produced. In this thesis, the effect of delayed winter pruning (LP), severe shoot trimming (SST) and their combination with or without removal of the second grape (LP+SST or LP+SST+SGR) in Assyrtiko vines on grape and wine composition was studied. The results of this research showed that the application of all the above interventions significantly delayed the ripening of the grapes, where the greatest difference was found in the LP+SST variant, with similar total acidity (TSS) during the harvest. Significant differences in quantitative yields were found at harvest, but overall no significant differences were found in the quality characteristics of both the must and the produced wine.
