Abstract:
The present study aimed to investigate the effect of different concentrations of IBA and IAA on growth parameters of Rosmarinus officinalis and Pelargonium graveolens. The cuttings were dipped in 250, 500, 750 and 1000 ppm of IBA (Indole-3-butyric acid) and IAA (Indole-3-acetic acid) solutions for 12 hrs and planted in poly bags containing mixtures of Soil, Sand and FYM in 1:2:1 proportion. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Data were collected on Survival percentage, number of sprouts, number of roots, root length, fresh weight and dry weight of roots at 60 and 90 DAP. The results showed that the IBA and IAA had significant effect on the root growth of Rosmarinus officinalis and Pelargonium graveolens. IBA treated cuttings showed better growth as compared to IAA. 750 ppm and 1000 ppm concentration of IBA recorded maximum growth in rosemary and geranium cuttings, respectively.
