Komparace vybraných pěstebních substrátů při zakořeňování bylinných řízků okrasných rostlin a jejich následné výsadbě
Hrabík, Pavel
This thesis deals with the level of influence of used substrates, during propagation of shrubs by herbaceous cuttings, to quality of their rooting. Also was tested the impact of these substrates for subsequent growth after planting into loose soil. Thesis includes literary section which summarizes information about plant propagation including factors that affect it and informations about substrates. Part of this work is an experiment that is thoroughly described there, including the methodology and results. The first part of the experiment was conducted in two terms and each term contained four variants. Each variant is one of the tested substrates. In these substrates were grown two taxa: Cotoneaster dammeri Schneid. and Cotoneaster salicifolius Franch. Parkteppich. Total it was evaluated nearly 3,500 cuttings. Furthermore it was 400 plants were planted in loose soil and after overwintering were also evaluated their quality parameters. The result of the experiment is that the quality of the substrate has a really affect to the quality of the rooting of cuttings. A major impact on their subsequent growth has not been confirmed.

Využití mykorhizy při vegetativním množení dřevin bylinnými řízky
Králová, Olga
My thesis tested efect of mycorrhizal fungy on herbal cutting. There was two terms propagation of four species. Syringa meyeri 'Palibin', Forsythia x intermedia 'Maluch', Cornus alba and Berberis thunbergii 'Rose Glow'. Experiment had two variantion and three repeats. Plants couldn't be nursed. Most of the results are inconclusive, because of the high losses. For species of Syringa meyeri 'Palibin' was demonstrated high influence of mycorrhizal fungi. There were also differences in terms. Overlay film had a positive impact only on Cornus alba. For species Cornus alba and Forsythia x intermedia 'Maluch' second term was more successful. When propagation of mycorrhiza has high potential.

Inovace množení dřevin bylinnými řízky v provozních podmínkách
Veselá, Jaroslava
The thesis is aimed at innovations in propagation of woody plants using herbal cuttings in the forest nurseries Pod Babím Lomem. Individual factors have been investigated on selected species of Cornus stolonifera, Deutzia scabra ´Plena´and Spiraea bumalda ´Goldflame´. Herbal cuttings have been sampled twice in the period between June and August 2018. Four variants have been planted after each sampling using different seedling trays and substrates. The results evaluated how the cuttings rooted and the total number of roots. The first samples have been found more successful from the rooting perspective. Among the different planting approaches, the control variant – with perlite-free substrate – showed the best results. The other way around, the worst results have been measured among the variants with substrate enriched with perlite. The results also point out the need for some improvements on the farm, e.g. the irrigation has been found insufficient.

Mykorhizní preparáty a jejich možné využití při množení okrasných dřevin
Hasalíková, Markéta
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.

Zakořeňování řízků dřevin v paperpotech a sadbovačích
Ambrožová, Klára
This thesis was written up at the Department of Breeding and Propagation of Horticultural Plants under Faculty of Horticulture Mendel University in Lednice. The thesis deals with rooting of woody species of chosen kinds of Ornamental wood. The experiment was performed for Berberis thunbergii ´Rose Glow´ and for Syringa meyeri ´Palibin´ in two terms (16.6.2016 and 1.8.2016) and in four variants. The fourth variant was for control only.

Využití mykorhizy při vegetativním množení dřevin bylinnými řízky
Ján, Jakub
The topic of the diploma thesis was the study of the influence of commercial mycorrhizal preparation on the rooting of softwood cuttings of two selected species of ornamental shrubs (Forsythia × intermedia 'Maluch' and Weigela florida 'Piccolo'). The main objective was to find out whether the mycorrhizal preparation can make the process of vegetative propagation more efficient and favourably influence the formation of roots. The used preparation contained arbuscular mycorrhizal fungi of the genus Glomus, two different amounts of the preparation were used. The experiment was carried out in the summer months of the year 2016. The experiment was founded in a plastic greenhouse on the ground of the Faculty of Horticulture in Lednice in Moravia (the Czech Republic), two main terms of propagation passed (in June and August) and one supplementary term passed (in August). The total number of adventitious roots, the number of branched roots, the length of shoots and the mortality of cuttings were evaluated. Mycorrhizal colonization of roots was evaluated in the laboratory under the microscope. The results of the experiment did not show that the used mycorrhizal preparation can positively affect the rooting of softwood cuttings, the application of the mycorrhizal inoculum did not improve the efficiency of vegetative propagation and did not provide convincing advantages. Mycorrhizal fungi did not stimulate the growth of cuttings, and in fact they did not influence the number of adventitious roots neither in Forsythia × intermedia 'Maluch', nor in Weigela florida 'Piccolo'. The only significant positive was that the Weigela florida 'Piccolo' had a higher number of branched roots after inoculation. The observation of roots under the microscope showed that the roots of both species were colonized by arbuscular mycorrhizal fungi, but the extent of colonization did not reach high levels. Mycorrhizal inoculation of propagation substrate cannot be recommended as an effective method that would improve rooting. However, it should be added that the experiment only passed for one year and the results were based only on one term of propagation. Thus the influence of mycorrhizal fungi on the rooting of plant cuttings should be the subject of further research.

Vliv délky skladování na kvalitu bylinných řízků dřevin
Horká, Marie
This thesis deals with the influence lenght of storage to rooting softwood cuttings on the chosen of ornamental woody species. The test was made on Ligustrum ovalifolium Hassk. and Pyracantha coccinea M. Roem. 'Dart's Red'. The test was being held in two dates, 17.6.2014 and 30.7.2014. For treatment of the cutting have been used 4 variants. The cuttings from first variant were planted immediately (the control), others variants were stored before planting for 12, 24 and 48 hours at 2 -- 5 °C.
