Schinus terebinthifolia Raddi, popularly known in Brazil as pink pepper or aroeira, has become a new source of agricultural exploitation for some farmers, notably located in the north of the state of Espírito Santo, the largest producing region in the world. Once it was a species that has been historically exploited in an extractive manner, where only what nature offers is explored, the need for the generation of scientific knowledge to understand its genetic potential in all agronomic areas is evident, starting with the large spread in scale of this species. Therefore, the objective of the work was to study the effects of indolebutyric acid (IBA) on the physiology and quality of seedlings produced by cuttings of the species Schinus terebentifolia Raddi under different concentrations of this hormone and different ways of application. The experiment design was a factorial in randomized blocks, in the 2x7 arrangement, the first being composed of two forms of preparation of the hormone (dilution in acetone or in water) and the second composed by 7 concentrations of IBA (0 mg/L; 625 mg/L; 1250 mg/L; 2500 mg/L; 3000 mg/L; 3750 mg/L and 5000 mg/L) with 5 blocks and 5 plants in each treatment. The addition of IBA favored the development and physiological aspects of the seedlings, produced from the hormone prepared with both, water and acetone. The quality of seedlings induced with IBA diluted in water was compromised with the addition of the hormone, whereas in seedlings treated with IBA diluted in acetone, the estimated dose of 1750 mg/L of IBA, promoted the better quality index (IQD) of the seedlings.
