The Peach (Prunus persica) propagation in Brazil is basically by grafting on rootstock propagated by seeds. Others methods for fruit tree propagation could be used for peach to obtain high quality plants. The objective of this work was to evaluate the effect of the 2,6-di-hydroxyacetoplenone applied previously to the indol-butyric acid in peach semi-hardwood cuttings prepared with different types of cuts in the bases. The cuttings were prepared with 12cm in length, 7mm in diameter, 4 shoots, and with different basal cuts (longitudinal incision, lateral incision and husk incision) and treated with 0 and 300mg L-1 of 2,6-di-hydroxyacetoplenone for 4h in aeration and then dipped on 2,500mg L-1 of indol-butyric acid for 5s. After treatment cuttings were planted in polystyrene trays with 72 cells with vermiculite as substrate, and place in greenhouse for 45 days. The 2,6-di-hydroxyacetoplenone application and basal cuts were efficient to increase rooting of peach ‘Okinawa’ semi-hardwood cuttings. These techniques can be used to make possible cutting propagation method for peach.
