Závorková, Hana ; Karlík, Petr (advisor) ; Černý, Tomáš (referee)
Lesser periwinkle (Vinca minor) is pretty common, perennial and woody plant, for centuries disseminated for her aesthetic and medicinal use. The aim of this thesis is to try to identify, if individual subjects disseminated throughout the Czech Republic may come from one or more sources or clones. It was collected a total of 135 individuals throughout the Czech Republic, and these individuals were grown for several years in uniform climatic conditions in campus of the Czech Agricultural University in Prague. For these plants were then performed a morphological measurements and statistical evaluation was performed by programs Statistica12 and Canoco5. From data obtained this way was revealed that the morphological features of individual plants are dependent on the type of site, and therefore it is clear that individuals grown on historically verifiable sites probably originate from one or several clones. Another aim of this work is to determine whether the periwinkle occurring in the Czech Republic differ in their morphological and physiological characteristics such as stem length, length and width of leaf, petiole length, number of nodes on the flowering stem and the ratio length / width of the leaf. The results implies the fact that individuals differ in morphological features depending on the location of their occurrence, such as parks, churches, cemeteries and forests. The results further shows to us that location no. 2 differs significantly from the other locations in the length of the stem, leaf length, number of nodes and in the ratio length / width of the leaf. This is confirmed by the results of the program as Statistica12 and the results of the program Canoco5.
