Hodnocení ontogenetického vývinu vybraného druhu dřeviny
Pavlíček, Michael
This paper deals with the assessment of ontogeny of the tree Tilia cordata Mill. ac-cording to the methodology of Raimbault (2006) in the city of Přerov. The catalogue cre-ated in the bachelor thesis shows all ten stages of tree ontogeny as described by Raimbault (2006) and displays typical individuals, all supplemented with additional data for each stage. In the next stage, two selected stages of the tree's development were compared, namely stages five and six. Basic dendrometric parameters such as the height of the tree, its girth, crown width, etc., were compared, and additionally the leaves were also com-pared in terms of their width and length, as well as trees’ fruits.

Posouzení dynamiky růstu a šíření jmelí bílého (Viscum album) na vybrané lokalitě
Horký, Jan
This thesis deals with growth dynamics and spread of white mistletoe (Viscum album) in the so-called „Fisherman's Alley“ in Přerov in 2021 and 2022. The research maps the degree of mistletoe infestation and basic characteristics of trees and examines their relationships. It also observes the relationship between mistletoe growth and climatic variables and maps the methods of mistletoe removal in the Czech Republic. In the observed period, the mistletoe infestation intensity increased in 22% of trees. The height and circumference of the tree affect the degree of infestation, the effect of age and health of the tree was less significant. The work showed a slight correlation between minimum temperatures in the first quarter of the year and mistletoe growth. The public administration is mainly involved in the removal of mistletoe in the Moravian-Silesian and Zlín regions, where pruning or felling trees are the most common methods. Chemical treatment usage is beginning to be used step-by-step.

Instalace a kontrola bezpečnostních vazeb stromů
Lacina, Jakub
Safety ties are an essential measure for securing trees that are exposed to various hazards such as windy conditions, storms, drought, disease and pests. Installation and inspection of safety ties are important steps for maintaining the safety and stability of trees, and therefore also for the protection of people and property in their vicinity. There are many factors to consider when installing safety ties, such as the type and condition of the tree, the type of tie and anchorage, terrain conditions, and the surrounding environment. Inspection of safety links should be carried out regularly. This article summarizes the most important factors regarding the installation and inspection of tree safety ties, including the procedures and techniques that should be used to properly install and maintain these ties. Proper installation and inspection of safety ties are key to the safety and long-term stability of trees, ensuring the sustainability and aesthetics of our environment.

Provedení detailního fytopatologického průzkumu a návrhy pro zlepšení stavu dřevin v Zoo Brno
Helánová, Sylva
The bachelor's thesis deals with the evaluation of the condition of woody plants, their vitality, health status, stability, operational safety and perspective. Furthermore, by proposing interventions to optimize their condition according to the methodology of the Nature and Landscape Protection Agency of the Czech Republic. A total of 200 trees were evaluated at the site - 11 small-leaved lindens (Tilia cordata Mill.), 11 hornbeam (Carpinus betulus L.) and 178 white oaks (Quercus petrea Liebl.). A field survey was carried out on these trees from March 2021 to March 2022. The results show that the trees on the site are not in good condition, their vitality and health are reduced. The presence of wood-destroying fungi such as Laetiporus sulphureus (Bull. Murrill) and Agrilus biguttatus (Fabricius, 1776) has also been discovered.

Hodnocení dřevin, rostoucích v rozdílných stanovištních podmínkách města Brna
Čadová, Barbora
The urban environment is very specific for growing of trees. The tree species in the cities are often influenced by complex of negative stressors and a different microclimate versus the free landscape. This diploma thesis deals with evaluation, monitoring, measurement and comparison of trees on two localities in central part of Brno. There are compared sites of Denis Settlement and part of the park under Špilberk Castle. Tracking took place during growing season from March to October 2017. It was found that the phenological development was faster on the surface of Denis' set for about 4 days. During the inventory was discovered sponge Hericium erinaceus on the species Koelreuteria paniculata from the Spilberk area. The translucency of light intensity by the crown decreased until August. The amount of chlorophyll in the leaves increased to July and in some cases until August.
