The experiment was conducted in the plastic house of the Horticulture Department Nursery/Technical College of Akre / Duhok Polytechnic University, during the period from 20 February to 1 July 2018.

This experiment include a study of the effect wounding (wounding and without wounding) and different growing media (sand + peatmoss (1: 1), loam + peat moss (1: 1) and alone peat moss) in the rooting of Barberry shrubs (Berberis vulgaris) hard wood cuttings.

The factorial experiment conducted by using Randomized Complete Block Design (RCBD) with three blocks and 10 cuttings for each treatment.

The important results indicated the following: although the wounding of cuttings had no significant increase in the rooting percentage (51.11% ), while significantly increase roots, shoots and leaves number/cutting, and dry weight of roots and vegetative growth.

And the best results of rooting percentage (56.67% ), root length, shoots length and dry weight of shoots characters obtained when cuttings planted in medium consist of loam and peat moss while the other characters was best when planted in sand with peat moss and in alone peat moss media.

For the dual interaction noticed that the non-wounded cuttings which planted in loam with peat moss medium gave the highest rooting percentage 60.00% while the planting of wounded cuttings in mixed of sand or loam with peat moss medium significantly improve all of the studied characters.
