Stevia rebaudiana Bertoni is a shrub that has sweetening properties on its leaves and can be used for medicinal purposes. The quality and vigor of the cuttings are essential for the later transplanting and acclimatization of the crop in the nursery phase, reason why it is important to find alternatives that guarantee an efficient rooting. The objective of the work was to evaluate the effect of Pectimorf ^® on the growth of Stevia cuttings in the nursery stage. The cuttings were soaked for two different times (30 and 60 minutes) at 10 and 20 mg L^-1 concentrations of Pectimorf ^® . As a control the conventional hormone indoleacetic acid (IAA) (30 minutes at 1 mg L^-1) and water were used as absolute control. Evaluations were performed from 20 to 50 days in the nursery. The addition of Pectimorf ^® to the concentration of 20 mg L^-1 increased the roots and leaves number, stem diameter, dry mass of leaves and stems, as well as Brix degrees in leaves of the apical zone on plants. The effect of Pectimorf ^® imbibition time at this concentration depended on the evaluated variable
