The aim of this study was to evaluate the semi-woody rooting of cuttings from 35 olive cultivars collected at two different times (April and August). The experimental design was the completely randomized in factorial 35x2, with 4 replicates and 25 cuttings per plot. The cuttings were standardized to 12 cm long and 4-6 internodes, with four entire leaves in the apical region. The treatment with hydroalcoholic solution of indolebutyric acid (IBA) at concentration of 3 g L-1 was performed by immersion of 3 cm from the base of the cuttings in the solution, for five seconds. The cutting was planted in sand and placed in greenhouse with intermittent mist. After 70 days, there was a significant variation in rooting among the olive cultivars. The cultivars MGS MANZ215 and MGS TAF390 showed higher rooting capacity. The cuttings collected in April presented higher rooting as compared to those ones collected in August for some of the cultivars evaluated.
