Abstract

Rooting trials of branch cuttings of jarul (Lagerstroemia speciosa Retz.), eucalyptus(Eucalyptus camaldulensis Dehn.) and mandar (Erythrina indica Lam.) from 30,15 and 10 years old trees respectively were conducted treating them with Indole Butyric Acid (IBA) powder (0.4 or 0.8% IBA) and setting them under open mist. In Jarul, IBA had positive effect on rooting success and rooting time. Both root number and root length per cutting was also enhanced by IBA application. In the leafy cutting of eucalyptus, rooting success was significantly influenced by the IBA concentrations. The highest rooting percentage was found in cuttings treating with 0.8% IBA. For mean root number and root length, IBA did not show any positive effect. In mandar, IBA did not show any positive effect on rooting success, mean root length and root number.
