Analýza vlivu půdní injektáže na stabilitu a vitalitu stromů
Kyslík, Ondřej
The bachelor thesis deals with the influence of air injection on the stability and vitality of the tree. The measurement was performed on three individuals of the species Tilia cordata Mill. Based on the data measured using pulling tests, a safety factor was calculated for each tree before and after soil injection. No significant changes were observed among the safety factors, and it can be confirmed that in this case the air injection treatment had no influence on the stability of the examined trees.
Physiological responses of woody species to urban environment
Petrouová, Lenka ; Lhotáková, Zuzana (advisor) ; Lipavská, Helena (referee)
Trees are an important functional element in urban ecosystems. The urban environment has a number of abiotic stress factors for trees and their interactions are based on the overall physiological condition of the trees. Abiotic stress factors include air pollution, space constraints, reduced water availability, increased temperature, and precipitation. In addition to abiotic factors, trees in the city face stressful conditions brought on by climate change, which are increasing in severity and have a measurable impacts on urban tree growth. Climate change is manifested mainly by elevated air temperatures, changes in quantity and distribution of precipitation, and increased concentrations of carbon dioxide in the atmosphere. This bachelor's thesis is focused on the responses of selected woody species in urban environments and their adaptive abilities in the context of changing climatic conditions. Growth is the main observable response of woody species to environmental changes. In particular, increased growth has been recorded in relation to rising temperature and carbon dioxide levels. Specific differences between woody species in functional parameters can be utilized to improve quality of life in human environments Trees are highly valuable in urban ecosystems and perform a range of functions,...
