The roses are considered as the main cut flowers exported from Brazil and also the most popular in the domestic market. Usually, roses can be propagated by grafting or cutting. The aim of this study was to evaluate the cuttings’ size and IBA concentration on mini-cutting rooting of roses variety Mary Rose. Cuttings were obtained from mother plants grown in gardens, with sizes of 3, 5 and 7 cm of length, 1.0 cm in diameter, and treated with IBA, in the concentrations of 0; 500 and 1000 mg L-1. The experimental design was installed in randomized blocks, in a factorial 3 x 3 (mini-cutting sizes x IBA concentration), with 4 repetitions and 10 mini-cuttings per plot. After 60 days rooted cuttings (%), cuttings with callus (%), primary sprouting, leaves and roots numbers, length of the three major roots (cm) and mortality (%) were evaluated. It is recommended to propagate roses by the use of mini-cuttings with 7 cm treated with 500 mg L-1 of IBA.
