Testování účinnosti vybraných povolených přípravků proti patogenním houbovým organismům dřevin v podmínkách in vitro
Ellingerová, Eva
This diploma thesis deals with testing the effectiveness of six selected approved preparations against pathogenic fungal organisms of woody plants in in vitro conditions. Specifically, they are Propizol (propiconazole), Phosphojet (potassium dihydrogen phosphate), Horizon 250 EW (tebuconazole), Ortiva (azoxystrobin), Topas 100 EC (penconazole) and Previcur Energy (fosetyl, propamocarb). Solutions of different concentrations (from 0.0001 % to 100 %) were prepared from these fungicidal substances, which were subsequently tested against the pathogenic fungal organisms Cylindrocarpon cylindroides and Sphaeropsis sapinea. The selected pathogens mainly attack conifers. In the case of Cylindrocarpon cylindroides, it is the genus Abies, and in the case of Sphaeropsis sapinea, the genus Pinus. All operations were carried out in the phytopathological and mycological laboratory at the Institute of Forest Protection and Hunting. Here, the tested pathogens were regularly checked and measured. After 13 weeks, the effectiveness of individual fungicidal preparations at given concentrations on 2 selected fungal pathogens was evaluated. The results show effective fungicidal preparations as well as preparations that, on the contrary, support the growth of the pathogen. The most effective fungicidal substance in both cases of pathogens was Horizon 250 EW (tebuconazole), which stopped the mycelium growth of both pathogens already at a 1 % concentration of the active substance.
Determination of Chlorophyll Content in Birch and Pine Trees Using Hyperspectral Data
Zachová, Kateřina ; Potůčková, Markéta (advisor) ; Brodský, Lukáš (referee)
The master thesis deals with the determination of the chlorophyll content in birch foliage (Betula pendula Roth) and Scots pine using hyperspectral data. The first part of the thesis concentrates on the literature search dealing with the methods of chlorophyll content in the foliage of selected plant species. In the practical part the emphasis is on the study of spectral reflectance curves and finding their relation to the chlorophyll content from the laboratory determination. Images taken with the hyperspectral sensor HyMap and spectral reflectance curves obtained with the ground ASD FieldSpec 3 spectrometer were available. Using the derived regression model chlorophyll maps were created for Scots pine for three selected locations in the Sokolov coal basin area.
Forest management of the Dominican order in the Mimoň region
Nejedlý, Ondřej ; Foltýn, Dušan (advisor) ; Hnilica, Jiří (referee)
This thesis deals with the forest management of the Dominican Order in Mimoň area. Specifically, it focuses mainly on the area of Hamr nad Jezerem, in the years 1931-1938 and the last years of the active duty of the Directorate of the Dominican forest management in 1945-1950. The emphasis of the thesis is based on the description of the previously uncharted historical chapter of the Dominican order in this area, especially with regard to the economic activity of the forest administration in this given period and legal aspects of the whole issue with the acquisition, loss and subsequent efforts to return these properties. The Fund no. 37 in the Archive of the Dominican order, deposited in the 1st Department of the National archive in Prague, was used as the main source, subsequently supplemented by specialized and professional literature, an interview with the legal representative of the Dominican order in Prague in the case of restitution and also by few internet resources. KEYWORDS Dominicans, forestry, Hamr, Restitution, Hospitaller Order of Saint John, count Hartig, hunting, hunting area, logging, the first Czechoslovak Republic.
