Hodnocení produkce a vitality sadebního materiálu lesních dřevin za použití hnojiv a přípravků s fytostimulačním účinkem v lesní školce Hejtmánkovice - Pasa
Térová, Radka
Final thesis on Assessment of production and vitality of forest woody species planting material with use of fertilizers and phytostimulatory agents in forest nursery Hejtmánkovice Pasa is a model study conducted in forest nursery. Topic of study was assessment of effect of phytostimulant WormsAktiv Stimul and slowly dissolving mineral nutrient Silvamix R30S with stimulants. In this context the biometric characteristics of douglas fir were assessed along with physical, physico-chemical and chemical characteristics of soil. Resulting estimation of biometric parameters of asessed plantlets after application of both preparates showed significant increase in root hair count of plantlets DG 2 minus 1. Results of this research report the effectivity of applied natural phytostimulants.

Analýza plodnosti a výskytu přirozené obnovy douglasky tisolisté na majetku "Lesy města Brna, a.s"
Parolek, Pavel
The objective of this thesis is using a series of field investigations to determine the status and potential of natural regeneration of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) on the area of interest "The Forests of The City of Brno, Corp.". Based on the results of field investigations we can deduce on fertility of Douglas fir, status and parameters of natural regeneration, intervals of seed years and dispersal possibilities of natural regeneration from the parent growth. The work consists of two different parts, theoretical and methodological (practical). The first part analyses theoretical aspects of the solved issue and the second part is devoted mainly to the methodological procedures. Of the 100 analyzed growths was located 86 % on nutrient habitats. In 77 % of cases occurred in the growths Douglas fir as wood disseminated. All growths over 80 years are spawning: 33% slightly, 58% moderate and 9% richly. Without natural regeneration was recorded only 17 % of growths. The height of Douglas fir grow under vegetation of 1,3 meters can be expected in the age of 11--12 years.

Vliv velikosti a krytí holiny na odrůstání kultur douglasky tisolisté
Paukovček, Michal
The aim of this diploma thesis was to determine what influence has a different size (cover) of clearing on growing cultures after the third growing season, time of planting and a type of planting material. The reaserch was realized on clearings with dimensions 55 x 70 m, 25 x 70 m, in Podsadba and on a big Kalamitná clearing (4,4 ha). There were used four provenances with or without an adjustment of root system. 10 parameters and signs were measured and recorded on each individual tree. Observed values were statistically evalueted and written comment was added. The results of reaserch confirmed that minor restoration elements are more suitable for culturing Douglas Fir as they provide a favourable microclimate. In these areas are lower losses and plants show a greater increase in aboveground part. In terms of time of planting, the most suitable appeared in the early spring planting dates. The adjustment of root system before planting had a negative effect because treated seedlings had lower gain and the losses were on average higher.
