The present investigation entitled “Effect of different concentrations of auxin hormone (IBA) upon promoting root development of stem cuttings in the ‘Scented Geranium’, Pelargonium graveolens L” was carried out at Medicinal and Aromatic Plants Research Station, (MAPRS) Rajendranagar, Sri Konda Laxman Telangana State Horticultural University, Hyderabad during December 2022 to February 2023. The experiments were conducted using a Completely Randomized Design (CRD) with three replications under a shade net house. Each replication consisted of seven treatments, which included a control group and six different concentrations of IBA (500 mg L-1, 1000 mg L-1, 1500 mg L-1, 2000 mg L-1, 2500 mg L-1, 3000 mg L-1). The results indicated, that among the various IBA concentrations tested, specifically IBA @ 2000 mg L-1 for stem cuttings, proved to be more effective than all other treatments in terms of various root parameters. It recorded the minimum days taken for root initiation and also recorded better results for the number of roots per cutting, average length of roots per cutting, length of longest root per cutting, fresh weight of roots per cutting, and dry weight of roots per cuttings.
Keywords: Scented geranium, terminal stem cuttings, different concentrations of IBA and root initiation
