The effect of pyrazine derivatives on secondary metabolites content in plant cultures in vitro II.
Hanzlíková, Tereza ; Tůmová, Lenka (advisor) ; Karlíčková, Jana (referee)
The main purpose of the theses was to find if the abiotic elicitor 2,4,6-trimethyl-N-(pyrazine- 2-yl)benzenesulfonamide has any influence on the secondary metabolites production in callus and suspension cultures of Hypericum perforatum L. The cultivation was taking place in the Murashige a Skoog (MS) nutrient medium enriched by the growth regulator - alpha-naphthyl acetic acid at the concentration of 1 mg.L-1 . The elicitor was added to the cultures at the three levels of concentration: c1= 100.0 mg/100 ml; c2= 10.0 mg/100 ml; c3= 1.00 mg/100 ml. The individual samples were taken after 6, 24, 48, 72 and 168 hours of the elicitor application. The control samples without the elicitor were taken after 6, 48 and 168 hours. The collected samples were dried and subsequently transformed into methanol extracts in order to determine secondary metabolites content (rutin, hyperoside and quercetin) by HPLC method. Release of these metabolites into nutrient media was also subject of this observation. The elicitation has influenced production of the secondary metabolites, particularly in callus cultures, wherein several statistically significant values, characterizing increase in their production, were measured. The highest content of rutin (0.169 mg.g-1 DW) was determined in callus culture after 168 hours when...

Future Through the Eyes of High School Students
Hanzlíková, Tereza ; High, Radka (advisor) ; Lukavská, Kateřina (referee)
This diploma thesis with the future through the eyes of senior high school students, especially with its contents and time location of these contents. The theoretical part presents the most famous time perspective theories and the relationship between adolescents and their future. The emhasis is on introducing czech and also foreign research on a similar topic. The empirical part has four goals: find out which future contents senior high school students are dealing with, 2. where these contents are located in time, 3. how important are the contents and 4. what is the relationship between the future contents and student's past and present. They were done semi-structured interviews within the first and the second goal, then these interviews were coded and interpreted by using elements of grounded theory. To answer the other two goals students filled out questionnaire Ten most important life events by Cottle. The discussion part presents results of the research and comparison with the results of other research. The most senior high school students deal (in the context of the future) with university study, profession, travelling, independence and making their own family. Key words: time perspective, future time perspective, future orientation, late adolescence, senior high school students
