Author(s): PS Chauhan, Chhavi Chadda, SS Singh
Abstract: The influence of Stik, Kinetin and Vit. K3 at various concentrations was studied on the rooting and shoots growth behavior of Geranium stem cuttings. Treated cuttings have been transferred to polythene bags. Initially small red color of protuberances appeared from the buds in all cuttings after six days of potting. Lower concentration of all appliedexogenous hormones was found more effective to enhance the sprouting, shoot growth and rooting behavior of treated cuttings in comparison to higher concentration. Poor results have been observed under the treatment of inverted cuttings for different parameters. Results revealed significant effects on different parameters. Highest sprouting percentage has been recorded under the treatment of Vit. K3 200 ppm in comparison to control. Stik 100ppm stimulated the growth rate of lateral branches in all the potted cuttings. Higher concentration showed inhibitory effects for different parameters in comparison to control. Rooting behaviour of all potted cutting was found significant and maximum number of secondary roots was noticed under the treatment of inverted cuttings.
