Abstract

The present experiment was carried out at the Instructional farm of College of Horticulture & Forestry, Jhalrapatan, Jhalawar during 2012–2013 to standardize the growing media and IBA concentration for the rooting of damask rose (R. damascena Mill) var. Ranisahiba cuttings. The trial was conducted in strip-plot design with 3 replications and 25 treatment combination of different growing media & IBA concentration. Results indicated that the combination of growing media and IBA significantly influenced the rooting of damask rose cuttings. The overall best performance was recorded in the cuttings treated with 200 ppm IBA and grown in the mixture of soil + sand + vermicompost (2:1:1) for the parameters like early sprouting (7.75 days), highest number of leaves per cutting (8.25), leaflet length (3.65 cm), roots per cutting (20.25 roots), length of root (7.05 cm), rooted cuttings (71.75%) and field survival percentage (71.25%), respectively. Among all the concentration of IBA and different media, rooting of rose cuttings treated with 200 ppm IBA under soil + sand + vermicompost (2:1:1) gave good results. The growing media and IBA early sprouting (14.00 days), highest number of leaves per cutting (3.25), leaflet length (2.25 cm), leaflet width (1.30 cm), roots per cutting (4.00 roots), length of root (2.93 cm) and field survival percentage (38.25%) recorded least value for the rooting with control in soil medium.
