The aim of this thesis was to verify whether it is possible to use mycorrhizal symbiosis in nursery production of selected varieties of highbush blueberries (Vaccinium corymbosum). In the theoretical part, a literature review on a given topic was elaborated. The methodology of the experiment was elaborated within the practical part. Practical experiments were carried out on experimental plots of the Institute of Breeding and Propagation of Horticultural Plants in Brno during 2018. During the growing season, growth indicators, physiological indicators, root system size and the degree of root colonization by mycorrhizal structures were evaluated. The results of my work clearly demonstrate the effect of mycorrhizal symbiosis on resistance to biotic and abiotic factors, especially drought stress. However, it should be noted that it would be useful to devote more time to researching ericoid mycorrhiza and to monitor more indicators to help us understand it better.
