Compounds of terpenic nature in mint plants and the influence of elicitation on them
 Jančová, Nikola ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
Diploma thesis is focused on study of compounds of terpenic nature in mint plants. Terpenic compounds are volatile hydrocarbons formed by several isoprenoid units with low molecular weight which cause the typical smell of plants. Presence of these compounds cause that plants seem to be fungicidal, bactericidal and insecticidal. Due to these properties, they can be used as botanical pesticides which are not toxic and no resistant organisms occur. Each plant contains relatively low concentrations of these compounds and therefore elicitors must be used for the increasing of terpenes amount. Elicitors activate defensive mechanisms in the plant leading to higher defense abilities and production of secondary metabolites. The identification and quantification of analytes was determined by gas chromatography in connection with mass spectrometry.

Possibilities of use of botanical pesticides and plant extracts in the protection of fennel, peppermint and thyme: certified methodology
 Pavela, Roman ; Žabka, Martin ; Kaffková, Katarína ; Smékalová, Kateřina
This publication is intended for growers of medicinal and aromatic plants (fennel, mint and thyme) and it is focused on their pests and diseases. It includes overview of suitable means and steps for elimination of the damage caused by these harmful agents by using biological way. The publication presents examples of both types of so-called botanical pesticides - commercially available products which contain extracts of biologically active substances from plants, as well as so-called farm products, for which it describes procedures for its preparation and using.
