The rose is a major ornamental species produced in Brazil. Its propagation is mainly made by cutting. In the process, cutting and substrate can influence the quality of seedlings. Given the above, the aim of the present study was to evaluate the best cutting withdrawal region and the appropriate substrate for vegetative propagation of pot rose cv. Yellow Terrazza®. The experimental design was completely randomized in a 2x3 factorial [two cutting removal of regions, apical and median x three substrates: commercial substrate, clay soil and commercial substrate mixture (1:1, v/v) and sand and commercial substrate mixture (1:1, v/v)], with ten replicates. The experiment was conducted in a tunnel covered with shadecloth.The cuttings were placed in polypropylene vase with 100 cm³ capacity, filled with each substrate. Were evaluated the length of roots, number of roots/cutting and dry matter of roots and shoots. The apical cutting propagates with higher quality seedlings of pot rose cv. Yellow Terrazza® than the median cutting, without influence of substrate type. Got better preparation of the pot rose cutting with clay soil and commercial substrate mixture.
