The thesis deals with the issue of defoliation after quality grapes. The work deals with the comparison of mechanical and manual defoliation. The first part deals with searching and displaying information with this issue. The second part is about my experiment, its processing and its own recommendations. I was able to do this experiment on the Plaček vineyard in Moravské Branice where I used 11 lines of Sauvignon blanc variety for the experiment when every line indicates another experiment variation. Defoliation zone of grapes took place since 7.6.2018. Manual defoliation always removed 1-3 leafs and other part from defoliation zone. Since 15.6.2018 we used a mechanized defoliation using the defoliator. The following experimental variations were made in the same terms both manually and mechanically. The last mechanical defoliation was on 1.7.2018 and we performed a defoliation variant as a control. The last attempts were made between 26.7 and 2.8.2018 where we used another method of defoliation zone of grapes for a purpose to slown down the ripening. During the ripening of the grapes their health and quality was monitored. In four weeks carried out the evaluation of qualitative grapes. The berry sugar content, Ph value, acid content, nitrogen content and other defoliation-related parameters were measured. All measurements were taking place at a school laboratory in Lednice. All data have been evaluated and we written own recommendations for winemakers and vineyard oweners.
