In this study, the rooting abilities of hardwood cuttings from ten rose-hip types collected in Gümüşhane in 1994-1995 were evaluated. The cuttings, taken in November, December and January, were planted in a perlit medium under a mist unit. In order to stimulate rooting, IBA doses of 1000, 2000, and 4000 ppm were used. The results showed that type 29-To-16 of Rosa canina had the highest rooting rate (86.25%), while type 29-Ke-27 of Rosa foetida had the lowest (3.33%). According to the average values of all the types, the best dose of IBA was 2000 ppm, and the best rooting time was November.
