This paper was carried out with the objective to verify the influence of shading, lesion in base cuttings and application of Indol-butyric acid (IBA) in rooting herbaceous star fruit cuttings. The cuttings were patronized with two leaves, and 15 cm of length. The experimental design was completely randomized, with the factorial 3 x 4, where the studied factors were techniques applied in the cuttings (shading and base incision ) and different concentration of IBA (0; 2,000; 4,000 and 6,000 mg L-1). The herbaceous cuttings were used as treatment controls. The shading was accomplished 45 days before the retreat of the cuttings in the branch, wrapping up the base of the future cuttings with black plastic ribbon and the base incision of the cuttings was accomplished in the preparation of the same ones, through two cuts in the base. The cuttings were maintained in chamber under intermittent mist and after 75 days, the rooting percentage, survival percentage, callus formation percentage, length of roots per cuttings, and fresh and dry weight of roots were evaluated. It was concluded that herbaceous cuttings without utilization of shading, lesion in base cuttings and application of IBA showed the best results of rooting (50.3%).
