Özet

In this study, rooting capacity was investigated for some genotypes of Rosa canina L., growing in four districts in the Lake Van Region in eastern Turkey. Hardwood cuttings were collected in November, December, January and February and rooted in perlite medium, using 0, 1000, 2500, 5000 or 10000 ppm IBA (3-indolebutyric acid). Highest rooting (65-70%) was obtained in cuttings collected in November and treated with 2500 ppm IBA, whereas cuttings collected in February and treated with 1000 ppm IBA showed the lowest rooting (2.5%). The internal IBA levels of November-cuttings treated with 2500 ppm were determined by high performance liquid chromatography (HPLC) after rooting, reaching a maximum of 1.525 mu g/g at 30 days after rooting.
