Vegetative propagation of Aesculus indica through stem cuttings treated with plant growth regulators.

摘要

Cuttage propagation of Aesculus indica was tested by treatments with different concentrations of indole-3-acetic acid (IAA) at 2000, 4000 (ppm), indolebutyric acid (IBA) at 2000, 4000 (ppm) and naphthalacetic acid (NAA) at 2000, 4000 (ppm) in dry formulation in the Forest Nursery, Faculty of Forestry, SKUAST-K, Shalimar, Jammu and Kashmir, India. The cuttings treated with IBA at 4000 and 2000 ppm had a sprouting rate of 75 and 50%, respectively, which was significantly higher than that of control and other treatments. The highest rooting rate (50%) was recorded in the cuttings with the application of IBA at 4000 ppm. The cuttings treated with IBA at 2000 ppm had 25% rooting rate. All other treatments along with control (talc powder) failed to induce rooting. It was concluded that IBA at 4000 ppm was a better-applied concentration for vegetative propagation of A. indica under Kashmir conditions.
