Resumen/Descripción – provisto por el repositorio digital
The Boxwood (Buxus sempervirens) is an important ornamental plant . Rooting of cuttings is slow and uneven. This work aimed to evaluate the effect of auxin on the rooting of cuttings in different seasons. The design used at different times was completely randomized with 8 treatments. The used concentrations of indole butyric acid (IBA) and naphthalene acetic acid (NAA) were: zero (control), 1500 mg L-1, 2500 mg L-1, 3500 mg L-1 and 4000 mg L-1 (latter only in the case of ANA). At 30, 60 and 90 day assessments of 1) number of roots per cuttings were made, 2) Total root length (cm), number of rooted cuttings (rooting percentage). At the end of the trial the count of dead cuttinds was performed. The data was subjected to an analysis set of experiments, analysis of variance with Tukey test (p≤ 0.05) and regression. For the conditions under which this test was performed is concluded that there are no structural barriers to rooting and the most propitious time to multiply Buxus sempervirens by cuttings is spring. Use of ANA showed better rooting rates using the IBA concentrations used in the concentration of 3500 mg. L-1 of ANA which showed higher percentages of rooted cuttings, with the highest number of roots per cuttings and greater total length them, accelerating the production of seedlings in nursery.
