Abstract
Ptilostemon chamaepeuce (L.) Less. has the potential to develop into a new floricultural crop but techniques for its propagation are required. Studies were conducted to investigate the effect of IBA application, the dipping in tap or warm water and various substrates upon adventitious rooting of leaf stem tip cuttings. Cuttings were dipped in ethanol solution (50%, v/v) of 0, 0.5, 1, 2, 4 or 8 g l-1 indole-3-butyric acid for 30 sec, or were dusted on their base with 0.6 g l-1 IBA. The bases of the cuttings were dipped and rinsed under tap water (20°C) for 2 h or dipped in warm water (40°C) for 1 hour and then were dusted with 0.6 g l-1 powder IBA. Peat moss, perlite, sand, vermiculite and their mixes were tested as substrates for cuttings treated with 0.6 or 2 g l-1 IBA for two continuing years. Treatments with IBA in powder form and warm water produced a significantly higher percentage rooting (24.4%) than the treatments with IBA in solution form. Best results were obtained by the use of vermiculite as substrate producing 84% and 64% rooted cuttings, for the two examined years.
