Abstract
Effect of various auxins (IBA, IAA and NAA) on different types of cuttings was investigated to determine efficacy of auxins in promoting ischolar_maining in carnation (Dianthus caryophyllus L.). Auxin and type of cutting significantly affected ischolar_maining traits. NAA was found to be more effective in promoting early ischolar_maining and inducing profuse ischolar_maining, ischolar_main number, fresh and dry weight of ischolar_mains and longer ischolar_mains. Among the auxins used, earliest ischolar_maining (18.69 days), highest ischolar_maining percentage (58.70 %), number of ischolar_mains (13.18), ischolar_main length (12.26 cm), and, highest fresh and dry weight of ischolar_mains (4.93g and 45.08 mg), respectively, were obtained with NAA @ 500 ppm. Tip cuttings responded better in ischolar_maining-characteristic of carnation - than basal cuttings, and recorded highest ischolar_maining percentage (73.02 %) and number of ischolar_mains (12.25), longest ischolar_mains (10.04cm) and maximum fresh and dry weight of ischolar_mains (4.27 g and 43.19 mg), respectively. Interaction effect of auxin and cutting type was found to the significant, and highest ischolar_maining percentage, (85.26%), number of ischolar_mains (18.36), longest ischolar_mains (14.81cm), and highest fresh and dry weight of ischolar_mains (6.85g and 68.02mg), respectively, observed with NAA @ 500 ppm in tip cuttings.
