Jaroslav Gongol, Monitoring of Norway Spruce (Picea abies (L.) Karst.) Wood and Phloem formation at the microscopic level.The thesis deals with monitoring of the norway spruce (Picea abies (L.) Karst.) wood and phloem formation on a research plot Rájec-Němčice during the growing season of 2012 and 2013. At weekly intervals from 5.4. to 7.11. were taken 11 -microbore samples from 6 different selected trees by using trephor. From taken microbore samples were created permanent microscopic preparations, which were further evaluated under a microscope. This thesis is focused on the evaluation of cambial activity and the process of formation of wood and phloem in relation to climatic conditions. Part of this thesis was also to evaluate the resulting annual growth ring character and the influence of the formation of wood on its properties and use. The findings were compared with the literature, which has already dealt with this issue. The average length of cambium activity in 2012 was 119 days and 112 days in 2013. The average growth of wood was 55 cells in the first year and 33 cells in the second year, when the average growth of phloem was 5.3 cells and 5.2 cells.
