The objective of this work was to evaluate the effect of four concentrations of indolbutyric acid on the rooting of plum branch cuttings (Prunus salicina, Lindl.) collected from plants treated with borax and zinc sulfate, in four periods. The experiments were conducted in a nursery with intermitent artificial mist conditions. The results showed a positive effect of cultivars, periods and IBA concentrations, and there was no effect of either borax or zinc sulfate on rooting of branch cuttings.
