Abstract :In this research, softwood apical cuttings were taken from Cotoneaster horizontalis Dcne. plants grown in Konya Alaeddin Keykubat campus in early July. The softwood cuttings were rooted in pumice medium under misting system insert ignore into journalissuearticles values(90-100 % humidity level); after treating with 0 insert ignore into journalissuearticles values(control);, 1000, 2000, 3000, 4000 ppm and 5000 ppm Indole-3-Butyric Acid insert ignore into journalissuearticles values(IBA);. Cuttings are investigated in terms of rooting percentage;  all the applications included in the control group were obtained 100 %. The highest root number was obtained from 4000 ppm dose application insert ignore into journalissuearticles values(28.90 number/cutting);; the lowest one was control group insert ignore into journalissuearticles values(18.62 number/cutting);. In terms of root lenght, the longest root insert ignore into journalissuearticles values(5.39 cm); was obtained from 1000 ppm IBA hormone dose application, the shortest root insert ignore into journalissuearticles values(4.50 cm); was obtained 2000 ppm hormone dose application. Also, the highest rooting area lenght was found 5000 ppm hormone dose insert ignore into journalissuearticles values(13.26 cm);, the lowest one was obtained from control group insert ignore into journalissuearticles values(6.61 cm);.
