Monitoring of selected metals in comercial bio wines
Bortlová, Alžběta ; Reichstädter, Marek (referee) ; Pořízka, Jaromír (advisor)
This bachelor thesis is focused on monitoring of selected metals in commercial organic wines. The aim of this thesis was to compare element content of organically produced wines with wines originating from other agrotechnical production system. Optical emission spectrometry with inductively coupled plasma (ICP-OES) was used for element analysis of wine. Statistical method analysis of variance has been used to assess whether the concentrations of the elements showed statistical differences between wines originating from organic production and wines originating from other production systems. Statistical differences were found in 3 of 20 analysed elements. Correlations between the element analysis and type of production system of grapevine were observed in content of the zinc, nickel and manganese.

Analýza užitkovosti v ekologickém chovu koz
Berková, Veronika
The goal of this thesis is the analysis of the milk yield on a particular organic farm breeding goats. The milk yield was monitored and evaluated in the control range 2015-2017. The data was obtained from the yield checks carried out by SCHOK (Association of Goat and Sheep Breeders) and from the farm's own records. The testing was run on 526 White Shorthaired goats yielding 760,08 kg of milk for standard lactation with a fat content of 3.4% in 2017. There has been a trend of rising milk yields on the farm since 2015 when the yield reached 627.77 kg of milk with a fat content of 3.02%. This trend was statistically highly potent (P<0.01), as well as the protein content (%) in milk which has dropped from 2.97% to 2.73% during the the same period of time. In addition, 184 goats on the 1st lactation and 177 goats on the 2nd lactation belonging to 16 father lines were evaluated. These lines were compared to each other by individual milk yield indicators. In the lactose content (%) the Krasus line dominated (4.83%) which showed statistically significant difference (P<0.05) compared to the Molch and Emil lines whose lactose content was the lowest (4.51% and 4.53% respectively). The 2nd lactation testing evaluated the number of somatic cells in the milk, with an average value of the group monitored being 1543.12 thousand of somatic cells per one mililiter. The highest number of the SC was measured in the Bera line (4437.17 thousand SC/ml) with statistical conclusiveness (P<0.05) compared to Bernd (758.5 thousand SC/ml), Curt (858.42 thousand SC/ml), Zub (444.24 thousand SC/ml), and Zuzek (696.77 thousand SC/ml) lines which reached the lowest values. In other observed milk yield parameters, the lines on both lactations showed marked differences in the values achieved but they were not statistically proven.

Možnosti ochrany proti šedé hnilobě hroznů révy
Dobiášová, Martina
This bachelor thesis describes the protection of the possibility of protection against gray grape varieties in organic and integrated production. In the first chapter, the bachelor thesis deals with the characteristics of Botrytis cinerea, we find the grape biology of the grape, it describes the mushroom originator, the symptoms of the attack and the noble rot. The next chapter deals with other rotations that may appear in the vine during vegetation. The third chapter describes the impact of decay on grape quality. In the last chapter the thesis deals with protection systems in organic and integrated production, against Botrytis cinerea.

Porovnání systémů ekologické ochrany u nových PIWI odrůd
Londová, Julie
The theoretical part of this thesis describes three different types of vinegrape productions in the Czech Republic – the integrated system, organic production and biodynamic way of vinegrape production. It describes the resistence and its mechanisms in the vine. A substantial part of the paper is focused on the fungal disease protection in organic grapevine production and finally the topic of elicitor-based preparations is discussed. The experimental part of the thesis concerns the comparison of three systems of protection against fungal diseases applied on grapevine. The Influence of these applications on the fungal disease infection and grape quality is monitored. From the results it is clear, that effectiveness of the three variants has been very similar and none of them was extremely distinctive either positively or negatively. As the most efficient variant was considered to be the EKO one, the author therefore recommends the application of the anti-fungal-disease preparations used in an ecological regime with the elicitor-based preparations included.

Možnosti ochrany proti vrtuli třešňové
Říhová, Petra
This thesis contains a short description of the Prunus avium L. its cultivation needs, pomological divergence and training systems. The main task of this thesis is focused on to the Rhagoletis cerasi. Taxonomy, bionomy, morfological description and spread of this pest. Part of the thesis is about natural antagonists and predators in context to the organic production. Description of the legislation and terms for organic production. Protection suggestions in this system against Rhagoletis cerasi L. The experimental part of this thesis was focused on to the efficiency confirmation of the selected organic friendly treatment products. Experiment was done on the Kordia variety of cherry Prunus avium L. in the orchard located in the Biele Karpaty region of the western Slovakia. There was low occurrence on the untreated variant in the time of sample colection. This might affect final results of this experiment.

Porovnání kvality hroznů z ekologické a integrované produkce ve vinohradnictví
Kovářová, Magdaléna
The theme of this work are two systems of production of grapes - organic and integrated production. Both systems are aimed at protecting the environment and its sustainability but there are differences between them. Organic production have a rules of treatment considerably stricter, especially in terms of authorized praparations of plant protection. The aim of the study was to determine whether if any of the systems has an influence on the quality parameters of grapes. Comparison was based on analytical measurements of selected quality parameters among five tested species of grapes. Tested samples came from the same habitat. The results were evaluated statistically by ANOVA method. The main finding was a positive influence of organic production on the pH of the grapes. For the other quality parameters, there was found no clear and statistically significant effect of treatment method.

Ekologické směry ve vinohradnictví a jejich vliv na jakost výsledných produktů
Špetík, Adam
The aim of this study was to compare the environmental guidelines, in both viticulture and winemaking in the Czech Republic. At present, every day intensifies pressure on environmental protection, which leads in viticulture and wine-friendly alternatives to favor production. The work is focused on explaining the the differences among individual directions, growing conditions and care. Among the conditions include a lot of aspects, from selecting a suitable place to a proper system of plant protection. In the integrated production system, organic and biodynamic production are precisely defined regulations and legislation permitted and prohibited substances, cultivation and cellar technology. The resulting product, a grape of it and made intermediate and wine is greatly influenced by the procedure in plant protection in the vineyard and winemaker intervention in the cellar and has a significant impact on the quality and the quality of this plant source.

The aim of this bachelors work with theme The Znojmo region, its integrated production and bio-production of grape wine is to rate the whole production and the meaning of integrated production and bio-production of grape wine in the region of Znojmo. It describes the history of viticulture and wine making in sub-region of Znojmo and also the legislation and systems of wine growing in Czech republic. The attention was paid to characteristics of wine growing sub-region of Znojmo, geological and climatic conditions. The gathered data about wine growing were displayed in tabular and graphic tables where i described grape yards in villages of the region, the characteristic types of wine with the average values of yield. Then I introduced two companies which concentrate on integrated production (Zemědělské družstvo Hodonice and Vinné sklepy Lechovice) and one grape yard with organic production (Vinařství Barabáš) which are key for the region. I also introduced smaller grape yards which concentrate on growing and making wine in this region and presented gathered information from harvest of grapevine (Vinařství Sádek, s.r.o. a Vinařství rodiny Čurdovi).
