Analýza tvorby dřeva buku lesního (Fagus sylvatica L.) na buněčné úrovni na výzkumné ploše Rájec - Holíkov
 Porvalík, Radim
The content of this diploma thesis is the analysis of the formation of beech wood (Fagus sylvatica L.) at the cellular level, ie xylogenesis in the research area Rájec - Holíkov, which is located in the Drahanská Highlands. Specifically, this study focused on the activity of cells in the cambial zone and the differentiation of the new annual ring on individual days (DOY) during the 2016 growing season compared to 2015, when samples were taken (Trephor tool) regularly once a week using so-called micro-bore. Permanent microscopic slides were created from these, which were subsequently examined. The activity of cells in the cambial zone was started in 2015 and 2016 in the last week of April at a temperature of 8.3 ° C. The zone of secondary cell wall (SW) formation and gradual cell lignification was evident two weeks after the onset of postcambial growth until the end of August. After the application of the Gompertz function, the creation of a new annual ring took an average of 91 days in 2015 and its size was 1252.7 μm. The year 2016 was similar, the size was 1229.2 μm. The average time of creation of a new annual ring was higher, namely 117 days.
