Stanovení genetické distance výchozích šlechtitelských materiálů řepky ozimé
Papanová, Michaela
Bachelor thesis is compiled from both the literature review and the practical part. The first one contains a treatise on oilseed rape and its main use. Attention is also paid to methods and history of breeding of this crop. An integral part is also an introduction to the concept of genetic distance and the importance of gene banks. The second part contains information about the research focused on determination of genetic distance in selected samples of oilseed rape by ISSR method. The results of the analysis were used to identify possible duplicates in the crop collection as well as to determine the genetic erosion of the samples. Similarly, the results can be used in the breeding itself, especially when selecting the parental components.
Investigation of the impact of stress factors on photosynthesis and transpiration of rape (/Brassica napus /L. var./napus/)
BICANOVÁ, Laura
The thesis deals with the influence of cold plasma treatment of seeds such as stress factor to the photosynthesis rate, transpiration and stomatal conductance of brassica oilseed rape (Brassica napus L. var. napus). The theoretical part is focused on the cold plasma, its application and effects on plant physiology, photosynthetic process and description of examined oilseed rape crops. The literature review is followed by the experiment which studies the influence of cold plasma on the physiological processes of plants. The seeds of oilseed rape have been treated with cold plasma in various intervals and cultivated plants were subjected to measuring device Licor Li 6400 XT. The results show that cold plasma treatment of brassica oilseed rape influences the physiological processes depending on the length of exposure and the plant age.
