Abstract: 

Rosemary (Rosmarinus officinalis L.), belonging to Lamiaceae family, is a perennial, medicinal and aromatic plant. The plant and its secondary metabolites are widely used in landscape designing and pharmaceutical, cosmetic and food industries. This research was conducted as two experiments in a RCBD (Randomized Complete Block Design) with six treatments (0, 1000, 2000, 3000, 4000 and 5000 mg l-1) and four replications in order to evaluate the effects of different concentrations of IBA and NAA on rooting of semi-hardwood cuttings of rosemary. Cuttings were treated in solutions of IBA and NAA for 1 min and held in plastic tunnel under mist system. After 70 days, the percentage of rotting, number of roots, average root length, the root fresh and dry weight, length of cutting, leaves and stem fresh and dry weight were measured. The analysis of variance showed that application of IBA and NAA had a significant effect on all the parameters studied. The highest rooting percentage was obtained at concentration of 1000 mg l-1 NAA (84%) and 5000 mg l-1 IBA (66%). The concentration of 4000 mgl-1 IBA was the best treatment on quality and rooting of the semi-hardwood cuttings of rosemary.
