Article Main Content

Production of adventive roots is a process induced and regulated by phytohormones where auxins play an important role in controlling the growth and development of them, with a direct influence on the regenerative ability of plants. The aim of this study was to compare the root induction and development on Sedum praealtum cuttings by the action of 3-indolylbutyric acid (IBA) and naphthylacetic acid (NAA) concentrations by root image analysis. Root length of plantlets showed that there was an interval between 0.1 and 1.0 mg/L concentrations of efficient root induction with a clearly decrease of it as IBA concentration increased, also as NAA treatment showed. In this work, the rooting response of Sedum praealtum cuttings evaluated by root image analysis showed the application of IBA as an efficient synthetic auxin for vegetative propagation.
