Možnosti využití arbuskulární mykorhizy při rozmnožování vybraných odrůd angreštu
Střihavková, Dana
This diploma thesis deals with usage of arbuscular mycorrhiza in the reproduction of selected varieties of gooseberries in plant nursery. The experiment was established in Brno in autumn 2018 and was completed in spring of the following year. In total, 60 plants of the ´Black Negus´, ´Carat´ and ´Rolonda´ varieties were evaluated, with half of the plants being inoculated with mycorrhizal fungus and the other half without mycorrhiza, as control plants. The following parameters were evaluated: extent of root colonization by mycorrhizal structures, content of chlorophyll, relative size of the root system, dry matter in the root system, substrate temperature and substrate humidity, root collar diameter and shoot length. The results show that inoculation with mycorrhizal fungus influenced the plant root system in positive way, which was reflected in the increase in root collar diameter. The inoculation with mycorrhizal fungus should also have a positive effect on the growth of the aerial part of the plant, the health and plant resistance to drought and pathogens.

Využití mykorhizních hub ve školkařské produkci okrasných dřevin
Linhartová, Anna
This thesis discusses the use of mycorrhizal fungi in nursery production. In the literature review there is summarized current knowledge regarding mycorrhiza and nursery production of ornamental plants. As a model plant for the experiment was used Spiraea bumalda "Anthony Waterer" and the experiment was conducted in the grounds of The Department of Breeding and Propagation in Lednice. There was applied mycorrhizal product Symbivit when planting in batch 6 g, 3 g, 1,5 g and 0 g. The plants were evaluated by parameters as plant height, diameter of root collar, the number of shoots. Then there were evaluated mycorrhizal colonization and volumes of roots balls in the laboratory. The experiment was described and evaluated statistically. The experiment resulted in the fact, that the more mycorrhizal product Symbivit is applied, the greater was the colonization. The mycorrhizal product had a positive effect on plant growth. The plants treated with product Symbivit in batch greater than 3 g proved a statistically significant difference in the monitored parameters compared to the control. There is also a economic viewpoint, the price of plants increases after the application of mycorrhizal product Simbivit.

Množení okrasných dřevin s využitím mykorhizy
Svobodová, Kateřina
The aim of my thesis was experimental prove of the influence of mycorrhizal product in the production of nursery propagation by herbaceous cuttings. On trial were selected three plant species, Deutzia gracilis 'Nikko', Forsythia x intermedia 'Maluch' and Syringa meyeri 'Palibin'. The experiment was based on two dates, and was conducted of the Institution of cultivation and reproducing of garden plants of Garden faculty of the Mendel University in Lednice. Evaluation was carried out in two variants, after three repetitions. The first variant was a control without mycorrhizal product, the second was supplemented with mycorrhizal fungi. It evaluated the number of roots, number of branched roots, cuttings and mortality rate of colonization. Differences in rooting and branching roots were among species, and between terms. The positive effect of mycorrhizal fungi was at Deutzia gracilis 'Nikko' and Forsythia x intermedia 'Maluch'.

Využití mykorhizních hub ve školkařských substrátech
Horváthová, Klaudia
The aim of my thesis in the experimental part was to prove new composition of nursery substrate with the adding of mykorrhiza. The evaluation where there was the kind Forsythia x intermedia Z. 'Golden Times used was done in four varieties of decorative substrate with the adding of different amount of inoculant. In the checking Hample there was no inoculant used. I evaluated these parameters: height of plants, number of shoots, length of shoots, diameter of root --collar, volume of root ball and rate of mykorrhiza. This experiment was done in the experimental area of the Institution of cultivation and reproducing of garden plants of Garden faculty of the Mendel university in Lednice. The obtained results are worked statistically. The theoretical part describes other authors'experience with studying mycorrhiza's symbiosis
