The results of Dracaena sub-populations research are submitted in this dissertation. Dragons Blood Tree is an endemic plant species growing on the Socotra Island. The thesis contains four scientific papers published or submitted for review in journals with impact factor and in peer-reviewed journal. The first article predicts sub-population dynamics on Firmihin where the ha sample plot inventory was carried out. Tree growth and mortality simulation has been created using a time horizon of 100 years. The second article is focused on growth dynamics of seedlings growing ex situ under controlled conditions. One hundred plants from Firmihin and Skand have been measured once a week for two years. The differences in growth dynamics and mortality for both groups of young plants in ex situ were evaluated. The third article also relates to Dragons Blood Tree regeneration and deals with a possibility of in-situ regeneration in the fenced area on Shibehon Plateau compared to Oam al-Cora school grounds. The team from Mendel University in Brno planted hundreds of seedlings in 2006, ever since the monitoring of growth dynamics and mortality continues. The fourth article deals with anatomy of secondary thickening plant organs. Xylem, phloem, parenchyma and vessels area of root, stem and branch was determined using 70 permanent microscope slides and processed by image analysis. The results were evaluated, compared and graphically interpreted.
