Porovnání různých způsobů hnojení a přihnojování okrasných dřevin ve školce
Brejchová, Lucie
The thesis deals with the issue of plant nutrition, fertilization, and additional fertilization of ornamental tree species in the nursery and provides an overview of the range of fertilizers that can be used just for nursery production. The tree production methods in the ornamental tree nursery have been described and part of the work is dedicated to substrates, plant pots and irrigation. In addition, attention is paid to the nutrient intake by plants and the demands of ornamental tree species on nutrients. The work is also dedicated to the fertilizing systems when growing tree species in pots and in free soil.

Minující druhy hmyzu (Insecta) na dřevinách v arboretu Mendelovy univerzity v Brně
Flajzarová, Andrea
The aim of final thesis was detect mining insects on a tree species in the arboretum of Mendel University from June to October 2016, determine the damage of domestic and exotic trees and determine influence on their health condition. In the research was found 42 species of butterflies from 8 families. The most abundant family were Gracillariidae (20 species) and Nepticulidae (14 species). The most abundant species were Cameraria ohridella, Phyllonorycter issikii and Phyllonorycter platani. The family Betulaceae was the most occupied from domestic wooden plant and the family Fagaceae was the most occupied from exotic wooden plant. Influence of damage wasn´t important on their health condition.

Minující hmyz na dřevinách ve vybraných parcích v Brně a okolí
Flajzarová, Andrea
In the three parks in Brno and its surroundings (arboretum of the Mendel university in Brno, the arboretum Křtiny and the forest park Kalvárie in Bučovice) the diversity of mining butterflies on ornamental trees was monitored in 2017 – 2018. The aim of the final thesis was to find out the spectrum of the mining butterflies, to determine a differences in species composition of the mining butterflies on the individual study areas and measure the degree of attack in host trees. A total of 47 species of mining butterflies were found. The most species were found in the arboretum of the Mendel university (31 species), the arboretum Křtiny (19 species) and at least species were found in the forest park Kalvárie (15 species). The most species who were found belong to the family of Gracillariidae (21 species) and Nepticulidae (20 species), the less species was from the family Tischeridae (2 species), Yponomeutidae (1 species) and Coleophoridae (1 species). The most abundant were the species of lithocolletinae, especially Cameraria ohridella on Aesculus hippocastanum, Phyllonorycter platani on Platanus acerifolia and Phyllonorycter issikii on genus Tilia. Against these species should be targeted a possible protection of host trees. The most species of mining butterflies were found on the wooden plant: Quercus robur, Fagus sylvatica, Quercus faginea, Quercus pubescens, Carpinus betulus a Ulmus glabra.

Výskyt plevelů ve vybraných porostech okrasných rostlin
Brabec, Tomáš
The aim of my thesis was evaluation of weed species spectrum in the stands of roses and thuja, which I did in the family company Zahradnictví Brabec. They specialize on growing ornamental trees and vegetables. I conducted the evaluation using mathematics and statistics methods. Overall, I found the occurrence of 24 weeds species, from which 23 species were in roses and 22 were in thuja. Among the most common weeds was in both crops Pigweed (Amaranthus retroflexus), Common lambsquarters (Chenopodium album) and Common orache (Atriplex patula).

Efektivita množení okrasných dřevin dřevitými řízky ve vztahu k termínu množení
Korbáš, Dalibor
The object of work was experimental prove of term-impact of taking cuttings for reproduction with woody cuttings by selected cultivars and determinating the most appropriate term for cutting offtake. The experiment was established in the company Pasič LTD. in Dolní Životice on the 9th of January 2015 and ended on the 27th of August 2015. For the experiment were chosen difficult rooted cultivars of conifers: Picea abies 'Nidiformis', Picea glauca 'Conica', Taxus baccata 'Fastigiata Aurea', Taxus baccata 'Repandens', Taxus baccata 'Overeynderi' a Taxus×media 'Hicksii'. There were set three terms for cuttings offtake: January, February and March. In every term were cutted 560 pieces cuttings from one cultivar with using stimulator for better rooting. On the basis of performed experiments can be recommended these months as the most appropriate reproduction term from experimental variation: Februar for cultivar 'Conica', 'Fastigiata Aurea', 'Overeynderi' and March for 'Nidiformis', 'Repandens' a 'Hicksii'.

Trofická specializace škůdců javorů (Acer spp.) v arboretu Mendelovy univerzity v Brně
Matejková, Veronika
Monitoring of maples pests were investigated in arboretum of Mendel University in Brno in 2015. There were registered 25 species of maples. Tree native species (A. campestre, A. platanoides, A. pseudoplatanus), four North American species (A. circinatum, A. negundo, A. saccharinum, A. saccharum), three Mediterranean to Asian species (A. monspessulanum, A. tataricum a A. cappadocicum) and fifteen Asian species. Most species attacked native species of maples and American maple A. saccharum. Eight monophages and one polyphagous species were found. All species reached low abundance. Polyphagous Operophtera brumata attacked 19 species of maples. Stigmella aceris damaged five species of maples, native A. campestre, A. platanoides and three Asian maples. Drepanosiphum platanoidis and Periphyllus aceris were found on two species of maples. Aceria macrochela, Periphyllus californiensis, P.testudinaceus, Phyllonorycter joannis and Drisina glutinosa were found on one species of maple.
