%X Pear producers are in search for earlier returns on their capital, a goal which is readily achieved with the cultivation of pear orchards in densely populated gardens. To investigate the effect of auxin treatments on the striking of vegetative pear rootstocks using methods of cutting and trench layering, a completely randomized experiment with three replications was conducted at the Agricultural College, University of Ilam in 2016. For the striking of the cuttings, hormonal treatments including Indole Butyric Acid hormones at 4 levels of zero (as the control treatment), 10, 100 and 500 mg/lit were employed. As for the methodology, the ends of the cuttings were placed in each of the hormonal treatments for 15 minutes. For the cultivation of cuttings, cocopeat and sand were mixed and used with a ratio of 1 to 2. The seedbed was disinfected in an autoclave for 30 minutes at a temperature of 120 ° C. The variables studied in this study included root length, root count, rooting percentage, and changes in root length. The results showed that the effect of the propagation method and the levels of auxin hormone were significant at 1% p-value on rooting percentage, frequency and root length. Still, regarding the variable of changes in the length of the branch, only hormone levels proved statistically significant. The results showed that the level of 100 mg/L of hormone is the optimal dose for using on rootstocks. Also, as for the type of propagation method, trench layering yielded better results than cuttings.
