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.
Ontogeneze versus věk u břízy bělokoré (Betula pendula Roth)
Čadová, Barbora
Ontogenesis and age are an inseparable part of every living organism, including trees. During their life, trees are undergoing changes in external and internal structure. The ontogeny is related to aging, which is in every tree different. Some trees are aging faster others slower. Raimbault (2006) in his methodology divided stages of ontogeny into 10 parts and completed a rough estimate of age. This thesis is focused on this methodology and deals with the 7th stage of ontogeny in silver birches (Betula pendula Roth.), which grow at two different sites. At the site with unsuitable conditions for growth and at the site with optimal conditions for the growth of trees. This work compares environment in which the birch trees grow, their age and overall appearance.
