Influence of rootstock on growth and fertility of choosen sweet cherry varieties
Englisch, Jakub ; Sus, Josef (advisor) ; Zíka, Lukáš (referee)
The main aim today is to improve the cultivation of fruits and intensification of production for satisfactory market supply quality products. This can be achieved by selecting an appropriate combination of base-variety and cultivation using perspective shape (spindle). The newly founded modern planting in the growing spindle-shaped when in use slow- growing rootstock up to several hundred more trees per hectare of orchards and fertility beginning to enter the third year, which is significantly earlier than in past years. In earlier planting was used, lusher rootstocks, but also used other forms of cultivation. Weakly vigorous rootstocks were represented in my attempt rootstock P-HL-A and Gisela 5.
The theoretical part focuses on the general demands of growing cherries, cherry growing importance and its botanical description, pests and diseases cherry rootstock influence on the variety and rootstock description. The experimental part of the work specializes in the characterization of habitat and experimental material, describes methods of assessment and method of the experiment itself, the experiment results and the conclusions drawn. The aim of the study was to assess the effect of different rootstocks on growth and fertility, selected varieties of cherries grown in the shape of the spindle in the third and sixth year after planting.
In the course of short-term plantings of cherries grown in the shape of the spindle it showed that rootstock P-HL-A variety 'Burlat' had a 19% increase compared with lusher 'Karešova' variety was planted on the same rootstock. Although the variety 'Karešova' had a smaller volume of crowns and reached compared to the variety 'Burlat' higher overall revenue (10.4%) and higher specific revenues, but the variety 'Burlat' reached about 10% higher compared to the average weight of the fruit variety 'Karešova'. Variety 'Sweet Early Panaro 1' on Gisela 5 rootstock had a 21% growth compared to the wilder variety 'Rita' (Gisela 5), higher total return (16.7%) was recorded in the variety 'Sweet Early Panaro 1', but specific (specific) revenues were a variety 'Rita' almost the same. Among the varieties 'Rita' and 'Sweet Early 1' Panaro was a big difference in the mean fetal weight. Variety 'Sweet Early Panaro 1' had a 40% higher compared to the average weight of the fruit variety 'Rita'.

Seasonal rhythms and hibernation of European turtles as a problem for their breeders
Tocauerová, Štěpánka ; Vrabec, Vladimír (advisor) ; Vejtrubová, Markéta (referee)
The thesis is focused on the seasonal activity of the European terrestrial turtles, which can be kept in captivity.The following species have been dealt with: Testudo hermanni, Testudo graeca, Testudo marginata and Testudo horsfieldii. The analysis was supposed to confirm the hypothesis that the species that lives that the turtle species living in the north is also the species with the least requirements when it comes to the microclimatic conditions.
The first chapter deals with the characteristics of these species. Both their Czech and Latin name is listed, the most famous subspecies classified, so are the most famous subspecies, the area where they occur is described and their appearance, including the typical features, what they feed on, how they reproduce, what conditions they require if they are to be bred and how endangered they are.
The next part deals with the seasonal rhythms of the turtles. The year is divided into several seasons or phases, i. e. the post-hibernation phase, spring, summer, pre-hibernation phase and hibernation. In each phase there is a description of both the active and passive behaviour of the turtle and of the way this behaviour is influenced by the time of sunshine, air temperature, rainfall or other factors. Examples of specific turtle behaviour that has been observed in different areas of the Mediterranean Sea, where they can be observed in the nature are given. What follows is a general characteristics of the hibernation and estivation and an explanation of the difference between the two.
The next chapter deals with the conditions for the turtle hibernation as a part of the breeding process, such as the preparation of the turtles for the hibernation and the ways to help them do so safely in our country. Some of the turtle keepers' opinions on this important subject, the right way of hibernation can influence other important physiological processes of the turtles are mentioned.
Then the recommended conditions for turtle breeding in our country are described.
The final chapter is charted information about the chosen turtle species ( the size of the shell, the height above the sea level in which they occurr, whether they hibernate or estivate and whether they are listed in the Red Book of Endangered Species and the CITES lists.
The analysis of the informaton that has been collected shows that the hypothesis that was formulated in the beginning of the thesis can be almost confirmed and that the Testudo hermanni seems to be species that is the easiest to breed indeed.

Optimizing the shape of the mower´s cover in terms of airflow at different arrangement of blades
Mihula, Lukáš ; Novák, Petr (advisor) ; Chyba, Jan (referee)
The aim of this thesis is to create a contemporary overview on the issue mulching using contemporary Czech and foreign literature. In the chapter Mulching is described in this technology and distribution mulchers and theoretical principle of their function and possible uses. The section Methodology already contains the actual description of the construction of the model shredder Vertical axis and a theoretical description of the pressure measurement using pressure strips on the mower housing. The actual results of the measurements and their interpretation, see chapter "Measurement Results". Subsequent comparison of measured values is described in Comparison of results. In the last chapter, Economic assessment is a calculation of unit costs set mower with energy means.

Comparison of accounting and tax accounts
VOŘÍŠKOVÁ, Andrea
The objective of this thesis is the analysis and assessment of accounting and tax accounts according to the current legislation valid in the Czech Republic, definition of essential differences between them, comparison of both systems including the possibility of their practical use. The theoretical part was focused on description and comparison of accounting and tax accounts from the accounting and tax perspective. The practical part deals with the analysis of accounting and tax accounts of a selected company. The comparison of accounting and tax accounts both from the accounting perspective and from the perspective of tax impact on a particular company was an objective of this part. Furthermore, it was assessed which system would be the most suitable for a particular business.

Influence of rotary mowers configuration on energy demands
Harkot, Mikuláš ; Chyba, Jan (advisor) ; Novák, Petr (referee)
This thesis aims to acquaint with the problems of mulching with vertical rotation axis. Emphasis is laid on energy demands and influences that may affect it. Especially arranging of knives of various construction types. In this thesis are introduced the characteristic of mulching machines and their comparison, a description of power indicators and losses and, ultimately, characteristic of elements of energy intensity.
The practical application of the thesis describes the methodology of work and measurements, which were carried out on the model of mulching machine. This part of the work also deals with the evaluation of the results from the measurement of power and torque depending on speed. In this thesis is carried out a statistical evaluation of measured values to validate the results. The results confirmed the existence of the effects of the arrangement of working tools on the energy intensity of mulcher. The last part of the thesis deals with the calculation of unit costs mulching machines per unit area and determination of fuel savings by changing the RPM.
