Iron Wood (Parrotia persica) tree as a forest species has many applications in urban green landscape. However, its reproduction and seedling production have not been studied in Iran. Thus, knowing the type of cutting and hormone treatments to increase the rooting of cuttings can be very effective. Accordingly, annual and perennial cuttings were prepared in January and June, respectively. Cuttings were treated with different concentrations of Indole butyric acid (IBA) (0, 500, 1000 and 2000 mg L-1). Perennial cuttings were not rooted in the present study. The maximum rooting percentage was observed in the treatment with 2000 mg L-1 Indole butyric acid in annual cutting. There were no significant differences in root length and root number in the 500 and 1000 mg L-1 treatments. The application of IBA decreased significantly the rooting time compared to the untreated control. The results indicated the effective role of IBA in extending the rooting percentage of Parrotia annual cutting.
