Abstract :In this study, softwood top cuttings were taken from 10-year old sweet cherry insert ignore into journalissuearticles values(Prunus avium L.); type grown in Alaaddin Keykubat campus in Konya. The softwood cuttings taken from in early June were rooted in pumice medium under misting system after treating with 0 insert ignore into journalissuearticles values(control);, 500, 1500, 2500 ppm and 3500 ppm Indole-3-Butyric Acid insert ignore into journalissuearticles values(IBA); under 2 different humidity of 85-90 % and 95-100 %. After having the cuttings rooted, obtaining shoots were investigated. In the research, all the cuttings were alive and getting root. Callus formation of control groups were in both of the humidity level. Rooting ratio showed high level with the hormon application. The highest rooting ratio was found from 1500 ppm IBA aplication insert ignore into journalissuearticles values(83.3 %); and 85-90 % relative humidity level. Length of rooting surface was found in hormon applications than control groups. Getting rise of hormon dose, length of rooting surface increased. The highest surface length were found from 3500 ppm IBA application insert ignore into journalissuearticles values(2.750cm); in 85-90 % relative humidity. In point of root number, the highest value showed 1500 ppm IBA application insert ignore into journalissuearticles values(10.0 number/cutting); in 85-90 % relative humidity. The longest root was found from 1500 ppm hormone dose insert ignore into journalissuearticles values(3.628cm); in the 85-90 % humidity level, the shortest one was 1500 ppm IBA hormone application insert ignore into journalissuearticles values(0.092cm); in 85-90 % humidity level. In point of root branching, the highest value was found from 1500 ppm hormone application insert ignore into journalissuearticles values(2.208 number/cutting);, neither control group nor 1500 ppm hormone application in 95-100 % humidity level were not obtained insert ignore into journalissuearticles values(0 number/cutting);.
