The sprouting dynamics of coppices on experimental clear-cuts of Podyjí National park
Pech, Jiří ; Bače, Radek (advisor) ; Čada, Vojtěch (referee)
This bachelor thesis is dealing with literature review of the subject coppice and coppice-with-standards forest in Czech Republic as well as in Europe. It is concerned with definition of these coppice systems, historical and current progress of coppice and its distribution in Czech Republic and European Union. Further questions of the thesis are, if there is any reason to continue or to renovate silviculture of coppice and if so, for what reasons and what is optimal rotation period in coppice. Description of principal tree species with sprouting ability in Central Europe are included in the thesis as well.
In the second part of the bachelor thesis sprouting ability in experimental research plots in National Park Podyjí are evaluated. The sprouting ability is evaluated for three principal tree species in Central Europe, oak, linden and hornbeam. The thesis compares interspecies relations in the initial growing speed of the shoots and the ability to produce the shoots in relation to diameter of the stump. Further the thesis is dealing with growing speed in relation to the amount of available light.
Measuring, after five growing seasons, in total of twelve experimental plots, discovered the highest sprouting ability by linden (87%), then oak (43%) and hornbeam (32%).
The thesis pointed out the significant interspecies differences in the ability to produce shoots. But the reliance of shoots producing on stump diameter has not been proved (for oak and hornbeam).
Because the relationship between the height increment of shoots and the amount of available light was not significantly demonstrate, it can be assumed, that experimental plots (forest clearing) are extensive enough and the sprouting ability is not limited by the amount of available light.
