The rooting (Exp. 1) was performed on DKW media supplemented with IBA (0, 0.25, 0.5 and 1 mg/L). During the rooting process the explants were maintained at standard (photoperiod of 16/24 h of light, 30 mu E). The best rooting of explants occurred in the treatment with higher level of auxin, IBA (1 mg/L), with 60% of rooting at day 25. Also, the higher IBA concentration significantly influenced the number and length of roots. However, the number of roots is high in treatment with 0.5 mg/L of IBA. Concerning, the ethylene production (Exp. 1), all the treatments of rooting, during the first day show a similar activity and successively the concentration tends to be low until the final of the rooting process in the control, while the curve of ethylene activity was significantly increased by the treatments with 0.5 and 1 mg/L of IBA until day 10. On the other hand, the IAAox activity shows a very complex behavior, with the higher value until day 10 with the dose of 0, 0.25 and 0.5 mg/L of IBA, with statistics of significant differences with regards to the higher dose of auxin (1 mg/L) of IBA. Also, the POD activity presents a complex trend, with a higher enzyme activity at day 21 in treatment with the high concentration of IBA (1 mg/L), while for the control the activity was constant during all the rooting steps. For the PPO activity, the higher values were shown at day 4 in the treatments of 0.5, 0.25 and 0 mg/L of IBA, with significant differences between the treatments, successively the curve declines until day 10 in the samples with 0.25 and 0 mg/L and returns to increase until day 15 with the dose of 0.25 mg/L of IBA and until day 21 with the control (IBA 0 mg/L), while with 0.5 mg/L of IBA, the curve descended from day 10 until the last step of the rooting, while for the higher dose of IBA (1 mg/L) the lowest value was showed, and with a little pick at day 21.
