Optimizing vegetative propagation techniques for Oroxylum indicum (Shyonak)

Present study endeavours to propagate Oroxylum indicum using vegetative propagation techniques. Stem cuttings and root cuttings are used as propagules. The cuttings were subjected to optimal environmental condition, well-draining rooting medium and treated with variable concentration of rooting hormones (IBA and NAA) for better root development. Data was documented on root development and overall growth. Vegetative propagation techniques yielded promising results, with plantlets developed from root cuttings displaying superior survival rates (55%) and rooting response compared to those from stem cuttings. These findings offer valuable insights for optimum propagation of O. indicum. Therefore, it is recommended that root cuttings be used as the preferred propagule for large-scale propagation and conservation efforts aimed at preserving this vital species.
