Initial study of predisposition of Norway spruce to bark beetle attack in relation to long term effects of multiple stress
KOTRC, Miroslav
This thesis is a contribution to understanding of predisposition of solitary Norway spruce (Picea abies [L.] Karst.) to bark beetle (Ips typographus (L.)) attack. The predisposition is estimated from long term effects of multiple stress, which are determined by tree crown transformation. By virtue of created model, it was documented that some environmental variables could have considerable effect on tree crown transformation. Tree crown transformation is generally considered a mirror of spruce health status.
Educational programme with elements of inquiry based earth science teaching at the 1.st grade primary school
SOUKUPOVÁ, Valerie
The aim of this work is to prepare an educational program with the elements of inquiry teaching (BOV) and at the same time to make sure whether the suggested activities from the point of view of the aims of teaching natural science at the 1 grade of the basic school are effective. This thesis shows some possibilities how to work out with this method and how to incorporate it to the process of teaching. As a purpose - built example there were used topics connected with the physiology of plants. Different teaching methods appropriate for the realization of BOV in the frame of the Educational program with respect to the relevant content of the textbooks of natural science are applied here. The thesis was dealt within the bounds of the project GA JU č. 065/2010/S a GA JU č. 078/2013/S
The influence of water stress on selected grass species and sward botanical composition
PAVELOVÁ, Lenka
The main goal of this thesis is to ascertain the influence of a water stress on regenerative and growth properties of grasses which were exposed to a water deficit and the influence on area composition of certain permanent grass vegetation. Assessment levels were based on container experiments. Each container contained selected class and subclass of a grass with different water regime demands. The aim of these experiments was to determine regenerative and growth abilities of chosen grasses which were exposed to water deficit and their ability to regenerate after drought during the grass branching phase. Another part of these experiments was to assess water regime impact on distribution of grasses in chosen areas. In the Czech Republic, grass vegetation is one of the basic food components for farm animals, mainly cattle, and it is an important landscaping element. It is also a component of forage industry which is a significant part of an agriculture output and the main goal in practice is to provide sufficient production of high quality,biologically valuable and healthy fodder.
