Abstract :This research was carried out in mist propagation unit of the Agricultural Research and Application Center of Tokat Gaziosmanpaşa University. Semi-hardwood cuttings of Hergo, Habego, Siberian Pearl, Leikora and Pollmix sea buckthorn cultivars were used as plant materials. Cuttings were taken in middle of the August and prepared in 15 cm length and treated with 0 insert ignore into journalissuearticles values(control);, 500, 1000 and 2000 ppm Indole Butyric Acid insert ignore into journalissuearticles values(IBA); concentrations. After ten weeks the cuttings were removed from the medium and callus rate insert ignore into journalissuearticles values(%);, rooting rate insert ignore into journalissuearticles values(%);, root length insert ignore into journalissuearticles values(cm);, root number insert ignore into journalissuearticles values(piece);, root wet weight insert ignore into journalissuearticles values(g);, root dry weight insert ignore into journalissuearticles values(g); and sapling success rate insert ignore into journalissuearticles values(%); were determined. As a result; rooting rates were 76.67-97.00%, root lengths were 8.33-10.76 cm, root numbers were 3.67-5.91, fresh root weights were 0.52-0.70 g, dry root weights were 0.09-0.16 g, sapling success rate varied between 71.23-87.45% but almost no callusing occurred in the cuttings of the sea buckthorn cultivars. The highest rooting rate and root numbers among the IBA concentrations were obtained from 1000 ppm application. Leikora had the highest rooting rate among cultivars. 2000 ppm IBA reduced the rooting rate of sea buckthorn semi-hardwood cuttings.
