Výskyt patogenů v porostu řepky ozimé
Pospíšil, Vojtěch
This bachelor thesis is based on the observation of the occurrence and discharge of pathogens in a oilseed rape stand in the locality of Praskačka. The experiment was sown in 2021 on the field of Pospíšil company. The frequency of infected plants by some pathogens was evaluated in four established plots in relation to the number of fungicides applied. On all plots ,white mould, alternaria spot, powdery mildew of crucifers and phoma stem cancer. Among the pests, the occurrence of striped flea beetle, cabbage stem weevil and pollen beetlewas observed in the stand.

Sledování výskytu houbových chorob u vybraných odrůd pšenice ozimé
Veselý, Michael
Abstract This bachelor thesis called Monitoring the occurrence of fungal diseases in selected winter wheat varieties deals with research on the occurrence of fungal diseases during vegetation on treated and untreated variant of common winter wheat (Triticum aestivum L. emend. Fiori et Paol.). The whole monitoring was performed in the Žabčice experi-mental field. In a total of twelve variants and three repetition of selected varieties.In the given period, pathogens of (Blumeria graminis, Mycosphaerella graminicola, Stagono-spora nodorum and Pyrenophora triticirepentis) were found. This work clearly shows the benefits of choosing the right varieties of wheat that are resistant to selected fungal diseases and can affect the profitability of growing.

Kvasinky Brettanomyces bruxelensis v technologii vín
Cháberová, Hana
During writing my Bachelors dissertation, I found out that wine is very vulnerable from the born of berries to the bowling. The most vulnerable time is after the alcoholic fermentation from the beginning of the malolactic fermantation, when wine is not protected. We can prevent from the minimization of infection and development of yeast the right hygiene of our cellars, suplhurating mash with the sufficient surface of SO2 during the maturation of wine, with the right cleaning of barrels or their well timed elimination from the service. We can also prevent from it keeping the barrels full and and sterile fulling the bottles.

Choroby a vady vín, jejich prevence a odstranění
Reichmannová, Šárka
This thesis focuses on defining basic defects and diseases of wine. It introduces factors affecting quality of produced wine following by definition of the basic terms such as defects and disease of wine. Particular defects are described and their causes listed, and the changes of defected wine are described in the area of aroma, taste and appearance. By each particular defect or disease there are suggestion how to prevent them and also there are mentioned methods to eliminate these defects and diseases with focus on presenting the up to date trends.

Sieglová, Kateřina ; Nachtigal, Petr (advisor) ; Laco, Jan (referee)
Kateřina Sieglová Detection of circulating antibodies to determination of autoimmuno diseases by means of imunofluorescence. Bachelor thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Medical Laboratory Technician Background: The aim of this thesis is to explore of coherence between the presence of antibody against anti brush border antibody (ABBA) and idiopatic bowel disease (Crohn's disease and ulcerative colitis). Methods: Evidence of connection idiopatic bowel disease with positive ABBA test is examine by two perspectives, which are used for selecting and comparising of data. The first way is comparison of the number ABBA positive patients with their diagnosis of endoscopic biopsy. The second way check the positivity or negativity of ABBA examination of all patients with diagnose of idiopatic bowel disease. Experimental part summarize by this way the results, which was done at the Fingerland institute of pathology since 2009 to 2011. Results: The survey showed that among all the ABBA-positive patients is a large group of those who don't have the morphological signs of Inflammatory Bowel Disease - 72,47%. 66.67% of patients with a clinical diagnosis of Crohn's disease, and 39.37% of patients with ulcerative colitis are ABBA positive. Conclusion: The results shows, that...

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.

Choroby a vady vín, jejich prevence a odstranění
Čačíková, Lucie
The purpose of this thesis is to analyse and discuss the problematic of present-day wine diseases and defects as discussed in specialized Czech and international literature. Moreover, it describes the origins of various defects of wine under aerobic and anaerobic conditions caused by bacteria, yeast or even lack of compliance of hygiene in winery procedures. Different ways of prevention of these defects and possibilities of their elimination are mentioned here as well.
