Ericaceae root mycobionts: diversity, distribution and interactions with neighboring plants
Kolátková, Viktorie ; Vohník, Martin (advisor) ; Baláž, Milan (referee)
The roots of ericaceous plants provide an environment to many fungal endophytes and mycorrhizal fungi.We can observe at least four mycorrhizal types in the family, of which the ericoid mycorrhiza (ErM) is spread the most. The Ericaceae are able to survive in many different and often harsh habitats all over the world thanks to this symbiosis (from the tropical cloud forests, to the arctic tundra heathlands). The group of fungi, forming this relationship, used to be seen as a few very well circumscribed ascomycetes, namely Rhizoscyphus ericae (Read) Zhang & Zhuang and Oidiodendron maius Barron species. With the development of molecular methods, it was expanded of many other species, some of which belonging to Basidiomycota, particularly the order Sebacinales. The diversity of ErM fungal community varies at different geographic locations and it can be influenced by factors such as altitude or the surrounding ecosystem. However, due to lack of further information, we still know quite little about the species distribution. Although they are primarily symbionts of the Ericaceae, some ErM fungi can colonize wider spectrum of plant hosts. Their effect on these hosts is not yet fully understood. Most importantly, they increase the vitality of ericaceous plants and favor them in competition with adjacent...

Možnosti využití erikoidní mykorhizy při rozmnožování vybraných odrůd zahradních borůvek.
Čižimská, Radka
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.
