An experiment was carried out to study the influence of shoot parameters on the effect of plant growth regulators on rooting of semi hardwood cuttings in betel vine (Piper betel L.) cv. Vellaikodi” in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar during November 2019. The experiment was conducted in Completely Randomized Design with thirteen treatments and three replications. The treatments comprised of using three growth regulators viz., IBA, IAA and NAA with four different concentrations of 50, 100, 150 and 200 ppm. The betel vine cuttings were dipped in the growth regulators for 12 hours and then planted in the polybags and kept inside the green house. The result of the above experiment revealed that the shoot parameters viz., number of sprouts per cuttings, number of leaves per cutting (cm), fresh weight of shoot (g), dry weight of shoot (g), and survival percentage of rooted cuttings were recorded the maximum in the treatment where IBA @ 150 ppm was used. The least parameters were observed in the control where the cuttings are dipped in distilled water.
