Efficacy of Different IBA Concentrations and Medium Types on Rooting of Euphorbia milii Cutting
Abstract
Cuttings of Euphorbia milii were treated with different concentrations (0, 1000, 2000 or 4000 mg/l) of indole butyric acid (IBA) before culturing in different media types [sand: peat moss (1:1, v/v), sand or peat moss] to investigate the impact of these treatments on rooting and shooting growth characters. Results indicated that treating cuttings with 4000 mg/l IBA before culturing in sand: peat moss (1:1, v/v) medium or sand medium gave the ultimate values of all investigated traits (rooting%, No. of roots/cutting, root length, root fresh and dry weights, No. of shoots/cutting, shoot length, No. of leaves/shoot as well as shoot fresh and dry weights).
Conclusion: from the economical point of view sand medium is preferable because it is cheaper than sand + peat moss (1:1, v/v) medium.
