Possibilities of AFLP technique in study of \kur{Beauveria bassiana} genetic structure
 BERANOVÁ, Kristina
Beauveria bassiana is widely used in biological control against the economically significant pests. Detection of morphological and genetic polymorphism among single species and strains in natural environment is important to study of the distribution and the effects in the ecosystem. The aim of this study was to determine the links of "local strains" with ecological aspects of biological control in protected zone of National park and assess the polymorphism of the population monitored in NP Šumava and exotic strains using molecular markers. There were analyzed 39 strains collected in the NP Šumava and the Krkonoše National Park in the Czech Republic and 11 strains from different countries and areas. The polymorphism of these strains was evaluated by different methods based on DNA analysis. In this study, the genetic variability is evaluated by AFLP markers. The results reveal that population from NP Šumava is very closed and the "local strains" can be very well characterized thanks these methods and compared with other strains from different parts of the Czech Republic and other countries. Thanks to these screening analyses, the strain Bba I101was determined for the preparation which will be used for bark beetle (Ips typographus) control in the National Park Šumava in the Czech Republic. This study was supported by grants GACR 521/08/H042, MSM 60076658-06, MZP SP/2d1/41/08.

The rutin content in amaranth (Amaranthus sp.)
 BERANOVÁ, Kristina
This work was aimed to the determination of the flavonoids of rutin in the leaves, stems and seeds of different kinds and species of amarant. Rutin is a phenolic substance, which belongs to big group of secondary plant metabolites. Most recently lot of attention is paid to quercetin and its glycoside {--} rutin because of its demonstrable positive effect on the human organism, mainly the antioxidant effects which prevents the atherosclerotic plaque and preroxidation of lipids and antiviral activities. The research orients to its potential anti-carcinogen activities. Thanks to these properties it became a common part of the human daily diet. Amarant could be a beneficial source of these substances. Content of rutin was determined by the micelar electrokinetic capillary chromatography (MECC) in the group of seven genotypes of amaranth. For the analysis a samples of leaves, stems and seeds were used, because of its high contents of flavonoids. The highest content of rutin was found in the leaves of the species A. cruentus {--} genotype Olpir (27 400 mg/kg of dry matter) and the lowest in the seeds of A. cruentus {--} genotype Monatana (25,3 mg/kg of dry matter). Results of this research are unique as they were never published before.
