Propagation of Ground Cover Roses with Woody Cuttings

V študijskem letu 2017/2018 smo proučevali razmnoževanje pokrovnih vrtnic z olesenelimi potaknjenci v zaščitenem prostoru. Namen diplomskega dela je bil proučiti vpliv različnih koncentracij (0 %, 0,1 %, 0,3 %) rastnega regulatorja indol 3-maslene kisline (IBA) na ukoreninjanje in morfološke lastnosti dveh sort pokrovnih vrtnic, in sicer \u27The Fairy\u27 in \u27Rody\u27. Poskus smo izvedli v petih terminih v rastlinjaku Fakultete za kmetijstvo in biosistemske vede Univerze v Mariboru. Ugotovili smo, da se uspešnost koreninjenja z dodajanjem rastnega regulatorja spreminja glede na termin potikanja. Tretiranje potaknjencev z 0,1 % koncentracijo rastnega regulatorja je značilno vplivalo na večje število ukoreninjenih potaknjencev v prvem in četrtem terminu, večjo maso pa so potaknjenci imeli v drugem in tretjem terminu potikanja. Potaknjenci sorte \u27The Fairy\u27 so bolje korenili od sorte \u27Rody\u27, in sicer najbolje v tretjem terminu, pri katerem smo dosegli 68 % ukoreninjenost potaknjencev.In 2017/2018 we studied the propagation of ground cover roses with woody cuttings in a protected area. The purpose of the thesis was to study the influence of different concentrations (0%, 0,1%, 0,3%) of the growth regulator indole 3-butyric acid (IBA) on rooting and morphological properties of two varieties of ground cover roses, namely \u27The Fairy\u27 and \u27Rody\u27. The experiment was conducted in five terms in the greenhouse. The cuttings were acquired from parent plants grown in the Botanical Garden of the University of Maribor in Pivola. On the basis of the results it could be concluded, that the treatment of cuttings with a 0,1% concentration of growth regulator had a significant effect on the number of rooted cuttings in the first and fourth term, and the greater mass off cuttings was observed in the second and third term. Cuttings of \u27The Fairy\u27 rooted significantly better than \u27Rody\u27. They best rooting was achieved in third term, when 68% of cuttings developed roots
