Možnosti hodnocení diverzity polních plevelů
Havlíčková, Kateřina
This thesis focuses on the diversity of weed vegetation and possibilities of its evaluati-on. The survey was carried out on fields of Mendel Univesity in Žabčice. Species di-versity was determined in the growth of opium poppy in 2013 and spring barley in 2014. Index of diversity were calculated according to the collected data. Spatial preference of individual weed species was designed by statistical analysis DCA (Detrended Corre-spondence Analysis) and RDA (Redundancy Analysis), processed on the basis of obtai-ned results. A total amount of 27 species was identified in opium poppy and 24 weed species were determined in spring barley. However, the vegetation consisted mostly by individuals of dominant species Echinochloa crus-galli, Chemopodium album and Lamium amplexicaule, in both monitored areas. It was found, that higher species richness are monitored on the edges of the fields, than their midpoints. Diversity of opium poppy was 0.17 and 0.36 of spring barely on experimental fields.

Hodnocení genetické diverzity genových zdrojů rostlin, programy, modely, využití
Oshea, Denisa
The bachelor thesis is a literature review on the topic of genetic diversity evaluation. The beginning is devoted to genetic diversity in general terms, its importance, its history, and its loss, that is irrecoverable and is regarded by many as the most important environmental problem. In addition, its protection, which is very important and in the Czech Republic is secured by the National program for conservation and utilization of plant genetic resources. The work also describes the methods of evaluation from morphological, through biochemical to molecular. There are described and compared mainly molecular methods such as RAPD, AFLP, RT-PCR, and others. The last part is devoted to a description of some plant genomes databases. One of them is for example The European Vitis Database.
