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.
