This study aimed to evaluate the effect of different concentrations of Indolebutyric acid (IBA) on rooting of Myrtus Communis as well as the best hormonal treatment for rooting of these cuttings. The cuttings with 15 cm long were prepared in December, January and February. To determine the best hormonal treatment of rooting, IBA with concentrations of 200, 1000, 2000 and 4000 ppm and a control group was used and the experiment was accomplished by a factorial completely randomized design with 3 replications and 30 cuttings per treatment under periodic fog in a sand bed. Then, the result of the number of rooted cuttings, the length of the longest root, fresh and dry weight of root were analyzed by SPSS software and Duncan test. The results indicated that there was a significant difference at 1% level between cutting times for all root traits. In addition, the result showed that the highest number of rooted cuttings was achieved by 2000 ppm IBA in December. This hormone with concentration of 2000 ppm had the greatest impact on the length of the longest root and fresh and dry weight of root.
