Vliv vybraných základních hnojiv na tvorbu kořenového systému okrasných dřevin
Krejčí, Jana
The aim of the thesis was to design an experiment to test the plants Caryopteris cladonensis ,Worcester Gold'. On the basis of this experiment should be carried out assessment of the basic types of fertilizers and their effect on the root system of experimental plants. The Experiment was carried out on 800 pieces of experimental plants, which were divided into four variants, and each variant consisted of four repetitions, so that was captured and the possible influence of the location of the plant. On the experimental plants were observed morphological parameters: the height of the plants, the number of shoots, number of sheets, the volume root, root collar diameter and Visual evaluation of the experimental plant. Evaluation of the results of the experiment on the root system of trees shows that between the versions there is a big difference and at the same time 62 you can assess that all the variants are very suitable for container growing method of experimental plants.
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 bezrašelinových substrátů v okrasném školkařství
Pavlíček, Matyáš
The main goal of this thesis was practical verification of influence on experimental nursery growing soil for progression and quality of produced crops. The trend of reimbursement of peat in soil is being a solution in european firms for many years. The test ratings were held on the grounds of Mendel university - Faculty of Horticulture in Lednice during the vegetation periond in the year 2016. The research was done on a Cotoneaster dammeri 'Coral Beauty'. All togerher there were four variants and four repetitions. The soil was supplyed by a German frim Gramoflor. There are constantly new materials and possibilities , which allows evolution of new soil recipes. Currently preferred materials are cut wood fiber (Lignofibre) and coconut peat (Cocopeat).
Možnosti stimulace vývinu kořenového systému sadebního materiálu lesních dřevin
Koudelík, Lukáš
The aim of this work was to verify in practice chemical products to support the growth of the root system and aboveground mass planting of forest trees in nurseries. These preparations were applied to plots in the nursery firm LESCUS Cetkovice, s.r.o. Application was processed according to the methodology of the chemical product manufacturer. Preparations were tested on major economic forest tree species. The monitored variables were the weight of the aboveground part, the weight of the underground section and height increment. The values were compared with those obtained from selections without treatment chemicals. Producers confirmed the efficacy claims for products Energen Fulhum and Galleko Růst. Unsuitable for use in nursery practice reflected product Galleko Kořen.
Využití fytohormonů při dopěstování sadby ovocných dřevin
Venuta, Rostislav
This diploma thesis focuses on the issue of the use of phytohormones in cultivation of young fruit trees. It includes a description of phytohormones and their effects on tree nursery yield. Four variants of products promoting branching, containing different active agents and concentrations, were experimentally applied on a set of plum tree varieties in a tree nursery. In the experiment, there was a control sample of plum trees without this treatment. The experiment was performed according to a predetermined methodology for the selection of varieties, well-defined dosage of the agents, development of young plants, concentration of the agents and the method of application. The trees were treated in a standard way within the nursery working. The photo documentation was taken continuously, the first documentation ten days after the last treatment in June, the second in mid-July and the last before the ploughing out in October. The experiment was evaluated according to predetermined criteria, especially by number of branches in the tree crowns. These data were adapted into chart evaluating the effectiveness of products and graphs were prepared for each variety and quality category of the yields. From these processed results, the products promoting branching without nipping off can be recommended for practical use on specific varieties. In this experiment, the most effective substance was 6-benzyladenine acid contained in the product Globaryll. Still, as a result of its use, the trees formed branches of the second and third grade and the crowns were too dense. This effect could probably have been avoided by using a lower concentration or single application of the agent. The obtained results of this experiment strongly support the effectiveness of the phytohormones on branching trees in the nurseries. This treatment makes qualitative shift in the cultivation of young fruit trees.
Vplyv vybraných faktorov na kvalitu škôlkarskej produkcie
Burgová, Jana
In the years 2008 - 2010 was realized trials with goal to influence the properties of the growing medium so, as the internal and external quality model plant (Viburnum opulus L.) grown in containers was significant increase. The whole of experiment was annually divided into equally two blocks, with different irrigation rates, which were also observed micro--climatic parameters both irrigation regimes. Was studied as well the influence of addition of soil conditioners on the properties of the growing medium. External quality of grown plants was assessed on the basis of morphological parameters (plant height, number of shoots, root collar diameter, dry matter of above-ground and root zone of plants and visual assessment of the root system) and internal quality based on the evaluation of physiological parameters (stomatal conductivity, chlorophyll fluorescence and chlorophyll content in the leaves). From the soil conditioners was investigated the impact of three commercially available agents with different composition and mode of action. It was a Hydrogel, TerraCottem and Agrosil LR. The properties of the growing medium, was affected by soil conditioners additive into the growing medium (peat--bark medium RKS II), but not enough for increase the quantitative parameters of cultivated plants, even the selected parameters in comparison with the control variant in both irrigation regimes were positively influenced, in order Hydrogel, Agrosil LR and TerraCottem
