Abstract
The use of Synthetic auxins is necessary for the initiation of adventitious roots in stem cuttings For this study, semi-woody cuttings of three commercial pot rose cultivars and a commercial rose rootstock, were used and then four types of rooting hormones including four hormones including indole butyric acid (IBA) and naphthalene acetic acid (NAA) from Sigma-Aldrich® and Iranian-made productions (Pro.But)® and (Pro.Nat) ®, each at seven levels (0, 250, 500, 750, 1000, 1250 and 1500 mg.l-1) were compared. To carry out this research, a factorial statistical format with a completely randomized basic design and 3 replications, each replication consisting of 8 cuttings, was used. The experiments were carried out on the studied varieties separately. Based on results, different cultivars show different reactions to rooting even after hormone application. For the three cultivars R. hybrida cv. Angela, R. hybrida cv. Red drift and R. canina cv. Natal brier It can be recommended that in order to achieve the highest number of roots as the most important characteristic in cuttings, the use of indole butyric acid (Pro.But) ® treatment with a concentration of 1250 mg. l-1 is quite effective and approved. In the cultivar R. damascena cv. Royal bonica, hormonal treatments effectively induced callus formation, but the roots that formed showed very limited growth. Overall, the IBA treatment had a higher quantity and quality of rooting than the NAA treatment with the same concentration.
