Vliv porostní struktury a druhové skladby na produkci dřevní biomasy výmladků v nízkém a středním lese
Procházka, Martin
In the last century, many coppice forests were transformed into high forests. Nowadays we can see the increase of interest in coppice forests and their management for wood production and nature conservation. The aim of this thesis was to provide the data from the experimental plot TARMAG Hády where the high forest was transformed into the coppice and coppice with standards. The goal was to study the sprouting capacity of different woody species and the production of biomass in those species. It was studying the dependence of biomass production on wood species. It was also surveyed if the number of standards affected the production of biomass. The research plot was measured twice, in 2014 and 2016. Biomass for each stump with sprouts in 2016 was found. The results of the experiment show that the woody biomass was affected by stand basal area previous forest stand. The biomass production was affected by the number of standards. The biggest production of biomass per individual was found in Tilia sp. Implementation of selective thinning is not necessary.

Hodnocení objemového přírůstu v lese v převodu na les střední na majetku Městských lesů Moravský Krumlov
Kašpárková, Martina
This bachelor thesis deals with the volume growth of the sessile oak (Quercus petraea (Matt.) Liebl) in the forest in the conversion to the coppice with standards forest. The research areas are located on the property of Moravský Krumlov Municipal Forests. The aim of this work was to evaluate of volume increment of the standards depending on the stand age, the thinning intensity and the set of forest types. The analysis of the measured data was made in STATISTICA program. The tests showed a dependence of the increment on the thinning intensity and stand age. The most suitable variant of the combination of observed factors, where the volume increment was the largest, is the young stand with the set of forest types 2H, and a stronger intensity of thinning.

Vliv vnějších a vnitřních faktorů na tloušťkový přírůst výstavkových dubů ve středním lese
Kollanda, Viktor
The aim of the thesis is to assess the extent of individual factors’ influence on the thickness growth of retention oak trees in the middle forest. The factors include height in 2008, habitat, release rate, vegetation age, the rate of epicormic branching and treetop health state and quality. To analyze the data, MS Excel and Statistica were used. The results were interpreted with the use of multidimensional regression analysis. The analyses resulted in regression coefficients which represent the relative magnitude of the increase of the thickness gain by the action of the individual factors. Not all the factors were shown to be statistically significant; their significance also differs over time.

Tloušťkový přírůst výstavkových dubů ve středním lese
Kollanda, Viktor
The aim of this thesis was to evaluate the diameter increment of sessile oak standards in a coppice-with-standards as related to release degree, site quality and age of the stands. We also tried to asses differences in diameter increment possibly induced by the above mentioned factors. Data processing and all analyses were done in MS Excel software. As a result, grafhical and tabellar presentation of differences between diameter incerements of partucular variants including the response of trees to release degree and combinations of other factor are shown. Statistical tests have shown that the diameter incerement of standards was related to investigated factors. Trees increased theit diameters on plots where release was done, but there were no significant differences between different release variants. Also, effect of age was also significant. On the other hand, there were no significant differences between increments on different edaphic cathegories.

Mensurational and ecological characteristics of oak reserved trees on selected area of 2nd vegetation belt
Šturmová, Iveta ; Šálek, Lubomír (advisor) ; Surový, Peter (referee)
The goal of this thesis is to find out mensurational and ecological characteristics
of oak reserved trees on selected locality in 2nd vegetation belt. The locality is situated
on upland region close to the town Kroměříž. A part of the thesis is measuring of crown parameters, their projection and development of the crown during competition process.
100 reserved trees were measured for this research, The average crown projection has value of 199,65 m2 which implies that maximal number of reserved trees per 1 hectare is 50. Furthermore, number of dead big branches and number of small and big hollows were recognized. The average number of big dead branches is 5,95. The small hollows occurred only in 8 trees and big hollows in 12 trees. Number of dead tres and hollows are influenced by competitive adjacent trees.
