Vliv regulace hroznů na kvalitativní parametry u odrůdy Savilon
Sadílek, Lukáš
This thesis deals with the influence of crop thinning on qualitative parameters of Savilon variety. The work can be divided into two parts. In the literary part of this work were described the qualitative parameters of grapes, the possibilities of crop thinning and other possibilities how to achieve the reduction of yield and increase the quality of grapes. In the second part of this work was made an attempt on the white PIWI variety Savilon. Crop thinning was performed in two variants. Then these variants were compared with the control variant without any regulation.
Hodnocení růstových a fyziologických vlastností odrůdy Savilon na několika podnožích
Vydařelý, Petr
This bachelor thesis deals with the growth and physiological properties of the Savilon variety on several different rootstocks. In the introduction of the thesis are described properties, aboveground and underground parts of the grapevine and problems of growth. Part of the work is devoted to the rootstock varieties, with description of its properties, the growth rate, the resistance to grape phylloxera, root nematodes and drought, the resistance to active lime content, compatibility and affinity with the grafted variety, requirements for soil conditions and cultivated rootstock varieties in Czech Republic. In the main part, the measured values of the experiment are analysed and suitable grain scion is determined for grafting on the Savilon variety.
Odolnost k houbovým chorobám odrůdy Tramín červený, pěstované v systému bioprodukce, v porovnání s vybranými interspecifickými odrůdami révy vinné
Kačer, Petr
The task of the thesis, focused on disease's symptoms of Plasmopara viticola (BERK et CURT.) BERL. et de TONI, 1888, Erysiphe necator BRAUN, TAKAMATSU, 2000 and Botryotinia fuckeliana (de BARY) WHETZEL, 1945 on Vitis vinifera L. plants, was done in 2 stations. The variety Traminer was compared with interspecific ones Savilon, Rinot and Vesna. The Traminer was compared either with or without treatment by ecological fungicides together with untreated control. The results about spreading of fungi diseases Botryotinia fuckeliana (de BARY) WHETZEL, 1945 were insufficient in order to find out the dependency. The mycelium with konidiophores appeared in both observed varieties of Traminer. The strong rains in August was the main factor of pathogen's occurence. Due to weather conditions of the 2015 the pathogenes Plasmopara viticola (BERK et CURT.) BERL. et de TONI, 1888, Erysiphe necator BRAUN, TAKAMATSU, 2000 were not observed, that's why the data about occurence of those pathogens are missing. The damage of the varieties Savilon and Rinot was caused by extreme level of sunshine and high temperatures, not by the fungi pathogenes. The variety Vesna did not show any damage caused by those factors.
