Hodnocení růstových, fyziologických vlastností a kvality hroznů nových PIWI odrůd révy vinné
Hromková, Veronika
The diploma thesis “Evaluation of growth and physiological characteristics and the quality of grapes of new PIWI grape varieties” contains information on qualitative parameters of the grapes in the must stage. A practical experiment on PIWI varieties ofErilon, Hibernal, Malverina, Mery, MI-4-120, MI-8-22, Rinot, Savilon and Vesna was used in the thesis and recommendationsfor agrotechnical practices related to the varieties and reaching the required qualitative parameters of the grapes were formulated.

Vliv regulace hroznů na kvalitativní parametry u odrůdy Savilon
Sadílek, Lukáš
This thesis deals with the influence of crop thinning on qualitative parameters of Savilon variety. The work can be divided into two parts. In the literary part of this work were described the qualitative parameters of grapes, the possibilities of crop thinning and other possibilities how to achieve the reduction of yield and increase the quality of grapes. In the second part of this work was made an attempt on the white PIWI variety Savilon. Crop thinning was performed in two variants. Then these variants were compared with the control variant without any regulation.

Vliv regulace hroznů na kvalitativní parametry u odrůdy Erilon
Mančík, Zdislav
This thesis has been drawn up at Mendel University in Brno, Faculty of Horticulture in Lednice, Moravia, at the Institute of Viticulture and Winemaking. The experiment was performed at a vineyard in the Mendeleum area in 2016. In my thesis I dealt with possibilities of the regulation of grape quantity, namely the Erilon variety, and impact of such operation on the quality of the grapes. It was found out that there was a statistically significant impact of the grape regulation quantity on yield of one plant, size of bunch of grapes and assimilable nitrogen content. In its literary part, the thesis was concerned with composition of the berries and qualitative characteristics of the grapes, variety description and today´s possible options of the grape quantity regulation. In its experimental part, the thesis focused on description of used analytical methods and an experiment on a white must grape Erilon variety was carried out. The regulation of the grape quantity was evaluated with respect to two options the results of which were then evaluated and compared with one another. Furthermore, a comparison with results of other authors was performed. After evaluation of the experiment results and climatic conditions of the year 2016 it can be stated that the regulation of the grape quantity by means of thinning (flower cluster thinning/cluster thinning) has a positive effect on the quality of grapes and that such method can be recommended for annual performance. In conclusion it can be said that some of the abovedescribed options of the grape quantity regulation has become an integral part of today´s modern viticulture regarding mainly.

Termíny a způsoby regulace násady hroznů a význam pro kvalitu hroznů
Hromek, Zdeněk
The thesis was written at Mendel University in Brno, Faculty of Horticulture in Lednice at the Institute of viticulture and vinemaking. In this task, I dealt with various options of regulation the quantity grapes, suitable term for realization of regulation quantity grapevine and its effect for grapes quality. The task is separated into two parts. The literary part of the task deals with qualitative parameters of berry vine, agrotechnical interventions that affects the maturation and grapes quality, and possibilities of regulation the quantity grapes. The second part was experiment executed on the blue grape variety Lemberger. Regulation was done in five versions and two ways of quantity regulation. These regulated options were compared with the control option without regulation. The evaluation of the experimental results states, that the regulation of grapes in the variety Lemberger has a positive effect on the quality grapes. From the perspective of qualitative parameters appears to be the most suited option halving of grapes on the plant within 30 days after flowering. The correct timing of regulation and method of execution is very important. In conclusion, the regulation of quantity grapes should be an integral part of modern viticulture.

Možnosti regulace násady hroznů a význam pro kvalitu hroznů
Bartošová, Martina
This bachelor thesis named "Options how to regulate the quantity of grapes and importance for the quality of grapes" was written at Mendel University, Faculty of Horticulture in Lednice at the Department of viticulture and winemaking. The thesis aims to describe methods used for controlling grape quantity and their impact on grape quality. This work also includes an experiment with blue interspecific wine grape variety Cerason. The experiment was performed in the vineyard line "V Mendeleu" in wine village Lednice. The goals are to trim grape flowers or fruits, to compare values of an average yield for a bush, an average bunch-of-grapes weight, an average berry weight, sugar content, a volume of titratable acids and pH value for each grape variety and to assess best results. I have determined five types of regulation, one of them was also a check option - without any regulation. Within the experiment, a method of bisection of grape fruits and a method of restricting a number of grapes to one per a bush was used respectively. After assessing, I recommend the best option for trimming the tested Cerason variety.

Porovnání systémů ošetřování ozelenění vinic ve vztahu ke kvalitě hroznů
Padalík, Ivo
This thesis summarizes all the currently available information regarding actual possibilities on the tending of the greening in vineyards. There is been stated the description of used systems of greening and the summary of mechanization intended to their tending in the exordium. The practical part of the thesis is being focused on researching of influences of various mixtures on the quality of grapes in combination with various systems of tending of the greening. There are being stated the most important parameters by laboratory analysis. These parameters have significant impact to the quality of wine, that is being made subsequently. The positive impact of herbal mixtures to the most of the monitored parametres was proved by performed experiment. There are stated some recommendations for the implementation which result of this thesis in the conclusion.

Hodnocení defoliace vinic s ohledem na stanovení rozsahu redukce listové plochy
Tisarová, Mária
This thesis deals with the evaluation of defoliation of vineyards with respect to determination of extent of leaf area reduction in the varieties Hibernal, Zweigeltrebe and Cabernet Moravia. The experiment was conducted in 2013 at the experimental sites in the cadastral area of Lednice in Moravia and Rakvice. The development of leaf area was evaluated by ADC device BioScientific Ltd. during three periods (June, July, August) in the phenological stages of flowering phenological stages of fruit development and ripening of the fruit phenological stages. From the measured data was determined leaf area index (LAI) and the extent of defoliation. Using analytical methods parameters of quality grapes were evaluated - the sugar content, pH, acidity, assimilable nitrogen, and others in order to determine the optimal time of reduction in leaf area of a vine. Part of this work was also the evaluation of operating costs for Defoliator.
