Abstract
An investigation was carried out to study the effect of different growth regulators on rooting of Premna integrifolia cuttings, a rare medicinal plant species. The various root and shoot parameters recorded significantly higher values when the cuttings were treated with growth regulators as compared to control. The higher rooting (86%) was recorded in the cuttings treated with 1000 ppm IBA against control (67.66%). The other parameters like number of roots per cutting, fresh weight and dry weight of roots, sprouting percentage, field establishment percentage etc. were also recorded higher in the cuttings treated with IBA 1000 ppm (96.5%) followed by IBA 2000 ppm (93.20%).
