Sažetak

The individual and combined effects of ampelotechnical treatments on the amount of sugar and total acidity of Zweigelt variety were examined by the three-year experiment. The investigations were carried out in the Feravino Ltd Feričanci production areas from 2006 to 2008. The experiment was set up by split plot plan with four replications. The main factor was determined by the crop load in three levels (24, 18 and 12 buds per vine), and factor by late hand partial defoliation at two levels (left and removed leaves in the zone of grapes). The amount of sugar in the must did not depend on any ampelotechnical treatments tested but only on the year as the largest and statistically significant sources of variability. The effects of the late and partial defoliation were statistically highly significant (P<0.01) in decreasing the total acidity of must compared to the treatment with abandoned leaves in the grapes zone.
