Vliv regulace násady hroznů na vývoj révy a kvalitu hroznů
Ťápal, Marek
The knowledge of location conditions, grapevine morphology and physiology are the fundamental assumptions for production of high quality grapes and final wine. The quality management should be considered as a comprehensive set of agrotechnical steps which influence the crop quality. The canopy management, especially bunch thinning, represents a group of actions influencing grapes quality parameters such as sugar and acids content, pH value and the content of polyphenols, anthocyanins and yeast assimilable nitrogen. The aromatic or phenolic maturity and plant vigor are influenced by the canopy management, too. The bunch thinning experiment with Malverina grape variety showed a very positive effect on sugar and acids content, pH value, aromatic maturity and plant vigor.
