Somatic embryogenesis (SE) represents potentially very suitable way of plant production - micropropagation - of plants in vitro. The process had been studied for more than thirty years and a lot of knowledge has been gained in the field though new ways based on new knowledge leading to improvement and increase of the effectiveness of cultivation protocols are still under focus in the field. Relatively recent discovery of aromatic cytokinins lead to new knowledge on very positive effects on different morphogenetic and physiological processes during both cultivation in vitro or in vivo treatments. This gave origin to the topic of the present thesis, which focused on study of the effect of meta-topolin (mT), aromatic cytokinin, on proliferation phase of SE on structural level of embryogenic lines of Norway spruce Picea abies (L.) Karst. The aim of the thesis is analysis of structural development of embryogenic lines with the use of anatomical preparations and quantitative stereological methods. The material represented three embryogenic lines: 107 and 34C were obtained from the Forestry and Game Management Research Institute from the lab of Dr. Jana Malá and the line AFO 541, which was used as a standard line. To compare the effect of mT with benzylaminopurine (BAP) on proportion of different...
