It was studied applications of different concentrations of 3-indolylbutyric acid (0, 20, 40, 60, 80, 100 and 200 ppm) in field conditions and cold treatment (15°C) on rooting of Stachytarpheta elegans cuts. From the data it was concluded that there was better rooting with 40 and 60 ppm concentrations in field conditions, and those treated with 40 ppm and later thermic treatment during kS days presented large number of bud growth.
