Porovnání metod stanovení obsahu mykotoxinů v obilninách
Boving, Veronique
In the Bachelor thesis I have dealt with a comparison of methods for determination of mycotoxins in cereals. The first part is a recent survey, in which I described the distribution of mycotoxins, I described the toxigenic fungi and produced mycotoxins. I noted the characteristics of the best-known mycotoxin and described some of the analytical method for the determination of mycotoxins. In the second part I focused on analysis of cereal samples. A total of 12 samples were analyzed by parallel analysis, that should determine the accuracy of the measurement. Analysis was performed using three methods of analysis, and ROSA for ZEA and DON, Reveal Q + for DON DON DON RAPID, Veratox for ZEA and the reference method was HPLC method. Difference was observed in the parallel measurements, the results of mycotoxins analyzed by various methods differed. We can not say which method is more accurate.

The role of atmospheric precipitation in anther dehiscence
Kampová, Anna ; Vosolsobě, Stanislav (advisor) ; Valuchová, Soňa (referee)
Anther dehiscence is an important process taking place at the end of the plant life cycle. This process consists of various follow-up steps which result in anther opening and pollen grains exposure. Good timing of the anther dehiscence must be synchronized with pollen grains maturation and flower opening. Atmospheric precipitation is a high-risk factor for the anther dehiscence. Male fitness of plants can be reduced when anthers open during poor weather conditions. The aim of this study was to investigate the effect of atmospheric precipitation, rain and dew, on Arabidopsis arenosa anther dehiscence. We observed that rain and dew led to a postponed final stage of the anther dehiscence. This caused delayed pollen release. The effect of aqueous and nonaqueous environment on the anther dehiscence was also tested. Experiments with transformation of A. arenosa using Agrobacterium tumefaciens were performed. Key words: anther dehiscence, flower opening, rain, dew, Arabidopsis arenosa, Agrobacterium tumefaciens, transformation

Možnosti pěstování některých méně pěstovaných ovocných druhů v ČR
Ambrosová, Lýdie
This bachelor thesis founds possibilities of lesser-known fruit species in the Czech Republic. It describes species Vaccinium vitis-idaea, Aronia melanocarpa and genus Rosa. It recounts their environmental requirements, methods of cultivation and reproduction in detail. Finally it summarizes usage of their fruits and their curative effects. On the basis of literary resources there are evaluated possibilities for growing these species in the Czech republic. Lesser-known fruit species can supplement the assortment of the traditional ones. They are unexacting in their requirements; they fit to processing in household and industries and they have high amount of nutrients.

Použití růží na území České republiky v první polovině 20. století
Sedlářová, Eliška
The first part of this diploma thesis is dealing with the usage of roses from the garden and landscape architecture perspective. Taxonomy of roses, their botanical description, spread, usage and history of growing and improvement were described. Another part of this diploma thesis focused on research of period rose assortment, more specifically on its range and possibilities of particular strains usage. Subsequently, availability of period assortment strains in the current market was determined. All information has been recorded in the summary table, which was further analyzed.

Záchrana genofondu vybraných starých odrůd růží z areálu Flora Olomouc množením in vitro
Remerová, Pavla
In the thesis "Saving the gene pool of selected varieties of old roses from the area Flora Olomouc using in vitro propagation" are listed procedures for sampling explants and primary cultures foundation varieties of roses Klimentina, Jan Palach, Fortissimo, Pastorale and Julius Fabiancs de Misefa. It was developed a protocol in vitro propagation of roses and selected media and culture conditions for the maintenance of multiplication in gene bank. Varieties Klimentina, Jan Palach, Fortissimo, Pastorale and Julius Fabiancs de Misefa formed its foundation. An integral part of the above results indicate that the formation of roots and convert rooted plants in non-sterile conditions. Finally, we tested the stability of donor plants and plant tissue using SSR primers in the varieties Klimentina, Jan Palach, Fortissimo and Julius Fabiancs de Misefa.
