Evolution of the genus Malus with a particular reference to old and local cultivars
Polcar, Václav ; Urfus, Tomáš (advisor) ; Macková, Lenka (referee)
The following work deals with the genus Malus in terms of the significant diversity that this genus represents. It summarizes a basic knowledge about the taxonomic position and world centers of the genus evolution. Part of the thesis also discussed reproductive mechanisms as a source of the genus diversity. The thesis then focuses on the species Malus domestica, its evolution and the hybrid origin. In this context, old varieties of apple trees, their significance and pomologically important regions of the Czech Republic are presented. An integral part of this work is also devoted to the protection of old varieties, its limits and possibilities. The protection of old varieties also encompasses the extensive orchard as an important agroecosystem. Finally, different Czech regions are compared with respect to the quantity of reported old varieties.

Analysis of car insurance offers in Czech Republic
POTĚŠIL, Dominik
This work deals with analysis of car insurance in Czech Republic. The aim of the bachelor thesis is to explain for what purpose is this insurance determined. The thesis is divided into the theoretical and practical part.

Diversity of Neofabraea species causing bull's eye rot in the Czech Republic
Pešicová, Kamila ; Novotný, David (advisor) ; Mazáková, Jana (referee)
Neofabraea is a genus of an important plant pathogenic fungi having worldwide appearance. Four Neofabraea species are responsible for bull's eye rot of pome fruits. The aim of this thesis was to investigate which of these species occur in the Czech Republic. 81 isolates were collected during a two- year period and they were identified using PCR fingerprinting (primers ERIC 1R and M13-core) and DNA sequencing (ITS, mtSSU and tub2). The results showed that species N. alba, N. perennans and Cryptosporiopsis kienholzii occur in the Czech Republic. According to available information, this is the second record of C. kienholzii in Europe. One isolate (KP4) failed to be identified as any of the species. KP4 is very close to C. kienholzii, but it can be distinguished both biologically and genetically. Furthermore, the aggressiveness of individual species was compared.N. perennans and strain KP4 proved to be most aggressive, the least aggressive is C. kienholzii. Two N. alba strains (KP36 and KP37) isolated from healthy apple fruit and leaf are pathogenic for apple fruits. Keywords: aggressiveness, Cryptosporiopsis kienholzii, Dermateaceae, Helotiales, apple tree, Malus, PCR fingerprinting, postharvest diseases Powered by TCPDF (www.tcpdf.org)

Vyhodnocení výskytu patogenů jabloně na lokalitě Lysice
Pavlíčková, Kristýna
In the Czech Republic and around the world are the most commonly grown fruit trees, apple trees. The yield and also its quality is dependent on the weather, location, but also largely on the proper protection against harmful organisms. The thesis contains an overview of the most important viral, bacterial and fungal pathogens, mainly the work is focuses on the agent of apple scab, Venturia inaequalis. In the locality Lysice were evaluated attacked three major fungal pathogens: Venturia inaequalis, Podosphaera leucotricha and Monilinia fructigena, on the varieties ´Idared´, ´Jonagold´, ´Rubín´ and ´Šampion´. The attack of leaves by agent of the apple scab was the most evident in the varieties ´Rubín´ and ´Jonagold´ for which was established middle occurrence class of pathogen. The attack of fruits was minimal, because protection was made correctly. For all varieties was evaluated high frequency of apple powdery mildew, while primary infection (15 to 53 % of monitored leaves). Due to the application of chemical protection were secondary infections weaker (19 to 37 % of monitored leaves) than primary infections. By Monilinia fructigena was the most attacked variety ´Rubín´ (56 % of monitored fruits). The variety ´Rubín´ was the most sensitive for all the evaluated pathogens. For particular pathogens was devised suitable protection system.

Multi - event Bonus - Malus System
Kaplanová, Martina ; Mazurová, Lucie (advisor) ; Branda, Martin (referee)
This work deals with bonus - malus systems for automobile insurance that distinguishtypes of claim. The first part of this work is definition of bonus - malus systems that do not distinguish types of claim and then their expansion just to multi - event bonus - malus systems. The main focus of the work is computation of stationary distribution for different systems, which means the distribution of classes in which the system stabilizes. Furthermore, there are several simulations of trajectory of insured through the system based on the number and type of accidents that they have caused. Finally, relative frequencies of classes in which insured is at the end of the simulation and the stationary distribution of the system are compared. Powered by TCPDF (www.tcpdf.org)
