Odrůstání kultur a porostů založených prostokořenným a krytokořenným sadebním materiálem na území LS LČR Jablunkov
Baselides, Andrzej
The aim of this diploma thesis is to evaluate the growth of cultures and stands estabilished using bare-rooted and ball-rooted planting stock on working-plan area, forest district Jablunkov. For this purpose a total of 23 stands were selected (evaluated) on 46 research plots on forest district Jablunkov. In addition, the two economically most important tree species were selected for research; Norway spruce (Picea abies L.Karst) and European beech (Fagus sylvatica L.). These areas were selected on the basis of geographic and typological differences of habitat. A minimum of 60 viable individuals from bare-rooted and ball-roted group were measured on each plot and also the root deformations of the selected tree species were measured. The following parameters were measured for each individual: the height of the above-ground parts, the last accretion, the thickness of the root collar, the number of branches, the length of the branches, the size of the assimilation apparatus. The following features have also been observed and evaluated: loss, vitality, damage, trunk shape, crown shape, and root system deformations. From the results it was found out that out of 23 stands, ball-rooted planting stock was evaluated as better in 16 cases, in 5 cases was better bare-rooted planting stock and in 2 cases no better variant was found. In assessing of the root system, it was found that up to 100 % of the root system deformation was found in both types of planting stock.

Vyhodnocení úspěšnosti obnovy lesa na kalamitních holinách LS LČR Jablunkov
Baselides, Andrzej
This work deals with artificial regeneration of the forest on the calamity clearing areas LCR LS Jablunkov. The main objective of this bachelor thesis was to evaluate the growth development of 5-8 years aged plantations of Norway spruce, silver fir, European Beech, pedunculated oak, small-leaved lime tree and black alder, after planting at water-affected sites. The other objective was to compare the results with growth at nutrient sites. The following parameters were evaluated: Losses, length of the shoot, last increment, diameter of the root collar, length of the needles, size of the assimilation apparatus of leaves, color of the needles, damaging, warp of the stem, vertical deflection of the stem, deployment height of forked trees, stem form and shape of the crown. Evaluation of trees´ root system was also part of this work. Results showed, that black alder and Norway spruce grow the best at the water-affected sites. Planting of small-leaved lime tree and pedunculated oak didn´t approve, on the contrary. Another problem was the fact, that there were serious deformations of the root system at all tree species. The last issue were the high losses due to the poor quality of the planting stock, improper way of planting, and large number of the occurring game. The comparison between water-affected and nutrient sites shows, that the trees grow better and reach better parametres and smaller losses at the nutrient sites.
