Rooting of Apical Softwood Cuttings of Cotoneaster horizontalis Dcne. with Application of IBA and Air Humidity
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 (90-100 % humidity level) after treating with 0 (control), 1000, 2000, 3000, 4000 ppm and 5000 ppm Indole-3-Butyric Acid (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 (28.90 number/cutting); the lowest one was control group (18.62 number/cutting). In terms of root lenght, the longest root (5.39 cm) was obtained from 1000 ppm IBA hormone dose application, the shortest root (4.50 cm) was obtained 2000 ppm hormone dose application. Also, the highest rooting area lenght was found 5000 ppm hormone dose (13.26 cm), the lowest one was obtained from control group (6.61 cm).
