This study investiges the rooting ability and the growth performance of lower and upper shoot positions and type of the cuttings, i.e. soft and hard wood and leafy and non leafy, of Tecoma stans (L.) Kunth. The cuttings were collected from 4-year old plants growing in the Chauras Campus of H.N.B. Garhwal University Srinagar Garhwal, Uttarakhand, India. The rooting ability of cuttings was studied under the treatments of indole-3-butyric acid (IBA) and Indole 3-acidic acid (IAA) under 0.0%, 0.3%, 0.4%, 0.5% concentration in both hormones. The rooting response was significantly (p < 0.05) better in 0.4% IBA compared to other treatments and control (0% IBA and IAA). The ratio of number of roots to rooted cuttings and length of root to rooted cuttings in the different treatments showed significant differences (p < 0.05). The rooted cuttings were further transferred, into the polythene bags and shifted to open nursery conditions. Under such conditions, the rooted cuttings treated with 0.4% and 0.5% IBA demonstrated the highest (90% to 100%) survival capacity in the lower portion soft wood and leafy stem cuttings. Plantable plant and plant height was greater in the 0.4% IBA concentration treatment. The results of the study suggest that rooting of soft wood stem cuttings having lower position and leaves could be an effective mean of regenerating to T. stans. Furthermore, the application of 0.4% IBA concentration treatment is appropriate for rooting of juvenile leafy stem cuttings in a mist chamber.
