Effects of Cutting Node, Rooting Promoter, and Media on Adventitious Rooting of Stem Cuttings in Clematis

There is little information about propagation of the cutting and seed, and management after propagation. To investigate the effective propagation method, cuttings of Clematis were collected and cutting experiment was performed at the greenhouse. Stem cutting lengths were 1 node and 2 nodes and peatmoss, perlite, and vermiculite were used as rooting media. IBA (4,000 mgㆍL⁻¹ soaking for 5 seconds and 500 mgㆍL⁻¹ soaking for 30 minutes) and Rootone™ were used as rooting promoter. Rooting rate of clematis cuttings usually took about 10 weeks. The 1-node cuttings increased the rooting rate by about 43% compared to 2-node cuttings. Rooting percentage of 1-node cuttings increased in the Rootone™ treatment about 7% more than in the control group. Using 1-node cutting is more effective in terms of the amount and management of the cuttings. Meanwhile, the rooting rate, and number and length of adventitious roots were largest in vermiculite and IBA 4,000 mgㆍL⁻¹ soaking for 5 seconds. Thus, when 1-node cuttings were stuck in vermiculite, rooting rate increased to about average 80-83%. Also, rooting rate in vermiculate is 25-29% and 13-39% higher than in peatmoss and perlite, respectively. Cutting in vermiculite increased by 9-13% after soaking into IBA 4,000 mgㆍL⁻¹ for 5 seconds and was found to be the most effective media and rooting promoter.
