The objective of this experiment was to evaluate the effect of the application method of indole-butyric acid (IBA) on rooting of peach herbaceous cuttings. The peach cultivars used were Delicioso Precoce, Jóia 1 and Okinawa. The cuttings were taken in September, 2001 and after the preparing, they were treated with 0, 1250, 2500 and 3750mg.L-1 of IBA for 5 seconds (concentrated solutions) and 0, 100, 200, 300mg.L-1 of IBA for 24 hours (diluted solutions). The best results of rooting were obtained with cultivar Jóia 1 (37,3%), although it was statistically equal to Okinawa (20,8%), both treated with concentrated solutions. Generally, concentrated solutions showed the best results of the evaluated parameters in this work.
