This bachelor thesis focuses on bad handling of bare-rooted and containerized seedlings of European beech (Fagus sylvatica L.) and Norway spruce (Picea abies L.). The aim of this thesis was to find out what influence the different length of drying of the root system of used planting material before planting, its follow-up and growth after planting and to determine critical values and times when plants are able to accept drought stress without significant losses and degradation of growth. The plants were planted as a freshly plants and after 1 and 2 weeks of establishment. The stress by drought was taking place in the shade, near the planting site for 0 to 48 hours. Along with planting, plants were tested to determine the water content of the root system or rootballs. The tested methods were the weight loss of the fine roots under constant heat stress, the measurement of the weight loss of the rootballs and the measurement moisture of the rootballs, using WHT 860, SM 300 and EMS sensors. The EMS sensor was found to be unpromising due to the inability to measure values in plants with too-dried rootballs whose plants did not show significant losses or degradation at the end of the growing season. Furthermore, it has been found that the seedlings of European beech are more predisposed to stress by drought, especially if the plants have before planting badly morphological conditions. On the contrary, the seedlings of Norway spruce are resistant to long-term stress.
Problems of Children Pre-School Age in Fragmentary Families
RAŠKOVÁ, Pavlína
My bachelor thesis deals with the observation of children from single-parent families in the preschool age,studying their behavior in the context of their problems. In the theoretical part, defines a family as a social group, its distribution, function and Discussed is also the view of history, which differs considerably from the present. Family child shows a complete male and female role behavior provides diverse background is a source of security and safety. Complete family, but these values are dysfunctional to some extent, lacking. Further explaining parent family, its origin and types, in which one pattern. The second is either replaced, and thus insufficiently fulfilling its role, or completely missing. Therefore, there is often emotional deprivation, which leads to unstable behavior. The practical part and apply an experimental method for observing a sample of preschool children affected by these issues individually. Finally, research confirm or deny it, based on detailed case studies, if the sample of children with behavior problems occur and emotional deprivation or not.
