Nerium oleander is a perennial shrub native to the eastern Mediterranean basin and Southeast Asia. As an ornamental plant grown in pots, it reaches heights of 1-2 m, with the appearance of a bushy shrub, with fragrant flowers, simple or double, colourful, blooming from spring until the end of autumn. With a very large adaptive potential, the species is one of the most popular in floral plants, as an indoor plant and where the climate allows, it can be grown on terraces and balconies, in hedges, alignments etc. The purpose of this study was to evaluate the impact of treatments with various rhizogenic biostimulators on the rooting potential of different types of Nerium oleander cuttings in greenhouse conditions. The experiment was performed in the HORTINVEST greenhouses of the USAMV Bucharest and there were determined the rooting percentage, the development of the root system and the aerial part, as well as some physiological indicators: photosynthesis, transpiration and stomatal conductance.
