    Aulonemia queko is a bamboo species found in some of the high Andean forests of Colombia, Ecuador, Peru and Bolivia. Currently this species is threatened by deforestation and unconscious destruction where it develops naturally, likewise there are no studies of any method of propagation that promote the survival of the same. In addition, A. queko is of social and economic interest because of the by-products that can be produced, such as baskets, handicrafts, etc. Therefore, the objective of the present research was to evaluate the effect of two growth regulators (Indole butyric acid (990ppm), Naphthaleneacetic acid (2204ppm)), and the use of substrates (Tn+A+Mo; Tn+Mantillo); in the ex situ propagation of A. queko at nursery and greenhouse levels at the Faculty of Agricultural Sciences of the University of Cuenca, where rhizomes of young plants from natural regeneration in the Molleturo forests were used. A DBCA with a 3ax2bx2c factorial arrangement was established, consisting of 6 treatments and 4 replications, generating a total of 480 rhizomes. The variables evaluated were: survival (%), number of shoots, height (cm), number of leaves, number of nodes, stem diameter (mm), root growth (cm³) and root biomass (g). For the analysis of the results, an analysis of variance (ANOVA) with Tukey's test (5%) was applied for parametric data and generalized linear mixed models (GLMM), with the DGC test (p<0.05) for non-parametric data. Statistical differences were observed for height at nursery level with 13.8 cm and root volume with 10.38 cm³ as well as in the plant x substrate interaction with 13.25 cm³. Finally, the variables stood out when the Control or AIB regulator was applied with the addition of mulch and in the case of the ANA regulator with black soil. This study seeks to promote the effective propagation of Aulonemia queko, to encourage reforestation in various ecosystems of the country
