Originally from the Mediterranean area, Rosmarinus officinalis (Fam. Lamiaceae) is a species widespread in most temperate regions of Europe and America with a significant economic impact due to the trivalent effect (ornamental, aromatic and medicinal). The purpose of these researches was to evaluate the impact of rhizogenic biostimulator Clonex-gel treatments on the rooting potential and some biochemical parameters of different types of cuttings in greenhouse conditions. The experiments carried out in the HORTINVEST greenhouses of USAMV Bucharest aimed to evaluate the rooting percentage, the development of the root system and the aerial part after rooting. Also, some biochemical parameters (assimilatory pigments and total soluble sugars content) were analyzed to assess the potential effect of the substances used to stimulate rooting on the biochemical composition of leaves formed on cuttings. The researches performed indicated that maximum percentage of rooting cuttings was determined in treated variants. The stimulation of the roots growth determined also an increased accumulation of assimilatory pigments and soluble glucids in the leaves.
