Vegetative Propagation of Tecoma stans: Influence of Shoot Position, Cutting Types, and Auxin Treatments

In this study, we investigated the rooting ability and growth performance of Tecoma stans using various shoot positions and cutting types, including softwood, hardwood, leafy, and non-leafy shoot cuttings. The cuttings were sourced from mature plants located at the Chauras Campus of H.N.B. Garhwal University, Srinagar Garhwal, Uttarakhand, India. We evaluated the effects of different concentrations of Indole-3-butyric acid (IBA) and Indole-3-acetic acid (IAA) treatments, specifically 0.0%, 0.3%, 0.4%, and 0.5%, on the rooting capabilities of these cuttings. Our findings indicate that the rooting of softwood shoot cuttings from the basal position with leaves is particularly effective for promoting rooting in T. stans. The study revealed significant differences (p<0.05) in the number of roots per cutting and root length across different shoot positions and cutting types under the control, IBA, and IAA treatments. These results provide valuable insights into optimizing vegetative propagation techniques for T. stans.
