Ornamental flowering plants are used worldwide for landscape design and as cut flowers. Most are imported from abroad and climatic conditions are different in their countries of origin. Although they produce seeds, these are often sterile and cannot germinate. Therefore, such species are multiplied vegetatively. In the present study it was investigated the propagation of two varieties of Mandevilla sanderi under the effect of three different rooting hormones (Incit 8, Radi-Stim® nr.1, Radi-Stim® nr.2), and two different rooting media (peat-perlite and peat). Untreated cuttings were considered as control. The results indicate that significant changes were obtained under the effect of the selected rooting stimulants, and that the rooting media did not influence the root initiation of the cuttings. Furthermore, no significant changes were observed on cuttings growth after transplantation. In conclusion, the current research shows that I8 and R2 increase the rooting of Mandevilla cuttings, and that the rooting media have no effect on the plants.
