Propagation of noble dendrobium orchid ( Dendrobium nobile Lindl.) by cutting was studied in two experiments. In the first experiment we evaluated the effect stem age on propagation success: mature stems - from already bloomed stems; and young stems – yet to bloom; and Nitrogen fertilizer application, from two sources: as Nitrate and Ammonium (respectively as Calcium Nitrate at concentrations of: 5.81 gL-1; 11.61 gL-1; 17.42 gL-1; and Urea at concentrations of 2.00 gL-1; 4.00 gL-1 and 6.00 gL-1 plus control treatments). We evaluated the following parameters: the number of cuttings stalks that launched shoots and/or roots, vigor, number of roots per plant and root length per plant. Factorial analysis of variance (stems age x source of Nitrogen; and age of stem x Nitrogen level) was applied using a Generalized Linear Model (GLM) approach. Where significant differences were observed, averages were compared using post-hoc tests (Tukey). Propagation success was higher using cuttings from mature stems (60.2%), a value 1.6 times higher than obtained with stem cuttings from young stems (38.0%). Application of Nitrogen, in both forms, did not influence any of the evaluated parameters. In the second experiment we treated cuttings from mature stems with Salicylic acid in 3 concentrations (0.10 mM; 0.50 mM; 1.00 mM and plus a control treatment). Evaluated parameters included proportion of cuttings stalks that launched shoots and/or roots, leaf length, root length, and number of roots per stem cutting. Factorial analysis of variance was applied with post-hoc tests. Application of 0.50 mM of Salicylic acid increased the proportion of cuttings stalks that launched shoots and/or roots by 20.5% relative to the control treatment.
