Root - shoot junction (collet) development
Hermann, Jiří ; Žárský, Viktor (advisor) ; Tylová, Edita (referee)
Although the root-shoot junction (collet) of adult plants is a well-identifiable part of the plant body, its development has, surprisingly till now, escaped serious research attention. The junction is a key region in the life of plants, as it connects two contrasting plant life environments and involves important changes in developmental programs - underground vs aboveground. The junction in angiosperms is first established during the embryogenesis phase of development in the form of the broad embryonic root- hypocotyl transition region, and it continues to develop further after seed germination during the individual's growth. The most important organ in this process is the hypocotyl, which exhibits considerable developmental plasticity, allowing extraordinary elongation in etiolated dark growth but also initiating formation of adventitious roots upon the deetiolation. During each stage of the junction's development, auxin signalling and polar auxin transport play a crucial role. Most of the research focuses on the development of the junction in the model organism Arabidopsis thaliana. The significance of the phylogenetic origin of the junction is also discussed from the perspective of the evolutionary origin of roots vs shoots and embryos evolution. This work aims to provide an overview of the...

Analysis of an individual playing perfomance for younger pupils
Frolík, Lukáš ; Buzek, Mario (advisor) ; Frýbort, Pavel (referee)
Name: Analysis of an individual playing perfomance for younger pupils Objective: The aim of this study is to determine the technical level of the younger pupils AC Sparta Praha and SK Slavia Praha against Bohemans 1905. It is specifically the percentage success collecting of the ball, pass and shot. Further, as I will be interested in the failing collecting, shooting and passing the ball skills. Methods: The method that I used for processing work is called indirect observation of previously recorded video. Data were processed mainly quantitative method. Results: Using the results, we found that a skill that is among hard according to the literature, and handling of the ball had the highest success rate of all monitored. Furthermore, what I found is that the players have many more attempts each game activities played under pressure than no pressure on the players. Keywords: Football, pass, shoot, ball collecting

Regenerative ability of slender speedwell (Veronica filiformis SM.)
Šerá, Božena
The experiment was focused on clonal development of Slender speedwell (Veronica filiformis Sm.) from small cutting stems without using of stimulative agents. Short stems from four various part of aboveground body were cultivated: main terminal part, secondary terminal part, small nodes, and big nodes. All different vegetative parts were able to produce roots, take roots in soil substrate and in semi-natural meadow, survive winter, and make flower. The species was more successful in company with these meadow plants: Lotus corniculatus, Medicago lupulina, Achillea millefolium, Plantago lanceolata, Taraxacum sect. Ruderalia, Trifolium repens and Crepis biennis. The best growth was confirmed for both of main and lateral terminal parts. These terminal segments had the greatest number of survived individuals, flowering stem, and weigh of dried parts.
