| Abstract:
To develop a mass propagation method for Hardenbergia violacea L., new shoots were prepared and used to compare the effects of rooting medium, temperature, photoperiod and concentrations of IBA (3-indolebutyric acid) and surfactant on rooting. The upper nodes of one-node cuttings bearing two leaves were cut half and placed in 16 ppm IBA solution for 1 h. The cuttings were then placed in rockwool cubes and maintained under 16-h photoperiod at 20°C on 4 weeks from the time of cutting to assess the extent of root formation. High percentages of rooting were observed, with the highest observed in the solution containing IBA and 0.05% surfactant. | |
