Patogeny denivky a možnosti ochrany
Šmídová, Markéta
The thesis deals with the most significant disease of the day-lily, the brown leaf streakiness caused by the fungus Aureobasidium microsticum in two habitats, Lednice and Ústí nad Orlicí in the year 2014. The intensity of infestation of the plants, the in-tensity of infestation on one shoot were evaluated. The infestation index and frequency of the pathogen in both habitats were determined. In the Lednice habitat 62 varieties of daylilies were evaluated. Different amounts of infestation intensity were recorded on them. The highest intensity of fungus infestati-on A. microsticum was recorded on varieties 'Forty Secon Street' and 'Clemenceaux', varieties 'Pandora Box' and 'Seal of Aproval' were attacked least. The highest intensity of infestation on one shoot and the defined index of infestation was at the varieties 'Forty Secon Street', 'Parian China' and 'Bonie Holey', while the lowest one was at varieties 'Ringlets','Golden Chimnes'. Furthermore the highest frequency of the pa-thogen was defined at varieties such as ' Kwanso', 'Atlas' and 'Rajah'. The lowest infe-station of the pathogen was at the varieties 'Seal Aproval'. All the varieties were attac-ked. In the Ústí nad Orlicí habitat 46 varieties of daylilies were used in this experiment. The highest intensity of plant infestation by the fungus A. microsticum was recorded on varieties 'Canadian Borde Patrol','Doll House' and 'Gold Reef', the least infested varieties were 'Real Wind', 'Mauna Loa' and 'Autumm Red'. The highest intensity of infestation on one shoot and the defined index of infestation were at the varieties 'Tonia Gay', 'Doll House' and 'Canadian Borde Patrol', while the lowest one was at the varieties eg. 'Barnabas' and 'Real Wind'. Furthermore defined frequency of the pathogen occurrence, where varieties such as 'Cosmic Carper', 'El Desperado' and 'Tanzanite' were infested the most and on the other hand the smallest rate was re-corded at the variety 'Franc Hals'. All the varieties were attacked. From all of the varieties from the infected leaves with the disease symptom the pathogen was isolated and microscopically analysed.

Hobzová, Kateřina
This diploma thesis on theme Hemerocallis L. species in garden and landscaping deals in the first part mostly with morfological and taxanomical characteristics of the genus Hemerocallis L., its breeding, species characteristics, growing and mainly using in garden and landscaping. The second part of the thesis is focused on the evaluation of the development of varieties of the genus Hemerocallis L. with emphasis on the period from the mid-19th century to the present. Development of varieties is evaluated in terms of the global development of species and varieties of daylilies and terms of offers genus Hemerocallis L. in the Czech and European countries.
