Micropropagated shoots of Stackhousia tryonii were exposed (individually or in combination) to indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), and I-naphthalene acetic acid (NAA) at concentrations 1, 2 or 4 g dm-3 with the view to induce rooting under ex vitro conditions. The treated microshoots were grown in a mist room for four weeks and assessed for survival, rooting percentage, number of roots and root length. The results showed that IBA at 2 g dm-3 was most effective in inducing roots. Mixing of two or more auxins markedly reduced rooting percentage indicating antagonistic effects. The results demonstrated the potential of combining ex vitro rooting and hardening in one step, with view to reducing costs of multiplying plants via micropropagation.
