Mykorhizní preparáty a jejich možné využití při množení okrasných dřevin

This diploma thesis deals with the influence of mycorrhizal preparations in the reproduction of ornamental trees and their recommendations for the production in growing nurseries. Two species of shrubs were chosen for the experimental part, Deutzia gracilis 'Nikko' and Weigela florida 'Piccolo'. The shrubs were propagated by herbal cuttings. The experiment took place in 2018 on the site of the Faculty of Horticulture in Lednice. After laboratory evaluation, the root colonization by arbuscular fungi has been demonstrated. The degree of colonization has not reached high levels, but we have seen their gradual increase. From the results it is noticeable that the preparations used did not influence the development of adventitious roots and the vitality of cuttings so it is not possible to label it as effective and recommending for the production in growing nurseries. It should be noted that the duration of this experiment was only one year
