Influence of growth regulators on propagation of culm-and branch cuttings of Bambusa vulgaris

Experiments were conducted to find out the effect of three growth regulators such as IAA, IBA and NAA each at six different concentrations viz. 50, 100, 150, 200, 250 and 300 ppm along with control on propagation of culm cuttings as well as branch cuttings of Bambusa vulgaris. The binodal cuttings were dipped in different growth regular solutions for 24 hours and the treatments were evaluated after 90 days of planting. No growth regulator treatment could exert significant influence on the culm cuttings with regard to propagation. There is no need of treating the cuttings of B vulgaris with growth regulators for successful propagation. Soaking the culm cuttings with normal water for 24 hours is suitable method for large scale propagation. However, IAA 100 treatment was found effective for propagation of culm-branch cuttings.
