Abstract

This study was conducted to investigate the effects of IBA, IAA and NAA on rooting power of semi - hardwood cuttings from Tilia. The cuttings were treated with 30, 40, 50 and 60 mg/l IBA, 100, 150, 200 and 250 mg/l IAA, and 20, 30, 40 and 50 mg/l NAA. The results were reported after three months. The following indicators were analyzed: percentage of rooted cuttings (%), number of roots of cutting and the average length of root (cm). The largest number of rooted cuttings was obtained using 40 mg/l IBA for most of the variants. The treatment with 200 mg/l IAA resulted in the roots with the greatest length. The average length of the roots is increased by treatment with 30 mg/l and 40 mg/l NAA. High doses of IBA, IAA, NAA will provide a weak, brittle root system, which reduces the chances of successful adaptation in replanting.
