Abstract

The impact of the term of defoliation of the zone of grape on quality and condition of plant health for the Sauvignon blanc variety The focus of the Thesis is to evaluate the effect of the term of defoliation of the zone of grape on quality and condition of plant health for Sauvignon blanc variety. The introduction of the theoretical part briefly characterizes the issue of leaf area -- factors affecting it. The next sections describe the green work and the attention is focused primarily on defoliation of the zone of grape -- the impact, the terms and the intensity of defoliation. The factors determining the ripeness and quality of grapes are briefly described as well individual qualitative parameters. The practical section describes he methodology used in the evaluation of the experiment of defoliation on four different terms and the results of the examined variants of defoliation are interpreted
