The peach propagation in Brazil is basically by grafting of cultivar on peach rootstocks propagated by seeds. An alternative for peach propagation could be by cutting. The objective of this work was to evaluate the peach rooting potential by semi-hardwood cutting throughout 2,6-di-hydroxyacetophenone (2,6-DHAP). Semi-hardwood steams of peach Delicioso Precoce, Jóia 1 and Okinawa cultivars were taken in December, 2001. The cuttings were prepared and treated with 0 and 300mg L-1 2,6-DHAP for four hours in aeration and after they were treated with indol-butyric acid (IBA) (200mg L-1 and 2500mg L-1). The cuttings were planted in polystyrene trays with vermiculite as substrate, and put into the greenhouse for 45 days. The application of 300mg L-1 2,6-DHAP applied before the application of 200mg L-1 IBA in peach semi-hardwood cuttings showed significantly increasing on the characteristics for cutting propagation studied in the present work and this technique can be interesting for peach propagation by cutting.
