As a honey plant, the value of hardy kiwi (Actinidia arguta) has been increased recently for using pollen. The aim of this research was to enhance hard wood cutting propagation efficiencies of hardy kiwi through the pretreatment of growth regulators. We examined the effects of type and concentrations of growth regulators on cutting of hardy kiwi. Three different growth regulators, NAA, IBA and IAA, were prepared by dissolving in distilled water and stem cuttings were kept in solution and they were planted in pearlite medium under greenhouse conditions. After 80 days, the number of rooted stem cutting, the number of root per stem cuttings, root length, root weight, new shoot length and new shoot diameter were determined on stem cuttings. The effects of growth regulators were found significant as statistically. By soaking in 1,000ppm of IBA solution, the survival rate was 82.5% and the rooting rate was 80.0%. For the treatment of IAA 2,000 ppm solution, the survival rate and the rooting rate were 70.0% and 70.0%, respectively. On the other hand, the survival rate and the rooting rate of the control which were untreated of growth regulator were 44.4% and 44.1%, respectively.
