This study is conducted to investigate the propagation of narrow-leaved ash (Fraxinus angustifolia Vahl.) from hardwood cuttings in a greenhouse experiment. Cuttings are obtained from 10-15 years old trees before vegetation season in a natural ash stands located in jurisdictions of Hendek Forest managementship, Adapazarı. Three type of medium were used for the experiment; 1) 75% sand + 25 % perlite, 2) sand 75 % + 25% gravel and 3) only sand as control. For hormone treatment, indole butirique acid (IBA) and indole acetic acids (IAA) were used at five doses (0, 100, 200, 2500 and 5000 ppm). Treatments effect on rooting percentage and the number of the roots were evaluated using factorial design analysis. Analysis of the data indicated that rooting percentages and the number of the roots were significantly affected by the main effects of rooting media and hormone and their interactions (P<0.05). None of the cuttings in sands and any of the cuttings without hormone treatments (control) had any sign of rooting. The highest rooting with 31.3 % was observed in experimental unit received sand + 2500 ppm IAA treatment. On the other hand cuttings on sand + gravel with 2500 ppm IBA treatment showed 18.8 % rooting rate. The highest average number of roots was calculated as 8.8 on cutting located in sand + perlite media with 2500 ppm IBA treatment. The number of roots on sand + gravel media with 200 ppm IBA was averaged as 9.2. Analysis of the data suggests that IBA and IAA 2500 ppm hormone type and doses in sand + perlite media had the best results for propagation of hardwood cuttings of narrow-leaved ash.
