these chemical regulators. It was applied to young rose plants, Rosa hybrida ‘Radrazz’ Knock-Out, at two different frequencies: once a day, three times per week, for seven weeks (Exp. 1), and five times a day, four times per week, for five weeks (Exp. 2). It consisted of passing a horizontal bar over the upper part of the plants. Significant results were obtained in the two trials, with an increase in the number of branchings from the most proximal metamers (of 102% and 97% in Exps. 1 and 2, respectively) and a reduction of the length of metamers of order 1 axes (of 8% and 9% in Exps. 1 and 2, respectively), resulting in a significant reduction in axis length in Exp. 2. A reduction in the length of order 2 axes during growth
