Vegetative propagation of native fruit species of páramo Thibaudia floribunda and Cavendishia bracteata by cuttings

Vegetative propagation of native fruit species of páramo Thibaudia floribunda and Cavendishia bracteata by cuttings

Cavendishia bracteata and Thibaudia floribunda (Ericaceae) are wild fruit shrubs native to the Andes region. This study aimed to characterize the rooting potential of basal and apical cuttings using naphthalene acetic acid (NAA) in different concentrations (0, 200, 500, or 1,000 mg L-1). In C. bracteata, the cutting position on the branch affected its sprouting and rooting, with apical cuttings presenting the best performance with auxin application. The rooting of cuttings was more successful in C. bracteata than in T. floribunda. NAA applications between 200 to 500 mg L-1 were more suitable for the propagation of C. bracteata due to the higher percentages of rooting and shoot production. For propagation of T. floribunda, the use of apical cuttings without the application of auxins is recommended. Adventitious roots in cuttings of both species were originated from parenchyma cells of the stem.

Cavendishia bracteata y Thibaudia floribunda (Ericaceae) son arbustos frutales silvestres nativos de los Andes. El objetivo de este estudio fue caracterizar el potencial de enraizamiento de las estacas basales y apicales utilizando ácido naftaleno acético (ANA) en diferentes concentraciones (0, 200, 500 o 1.000 mg L-1). En C. bracteata, la posición de la estaca en la rama afectó su brotación y enraizamiento, las estacas apicales presentaron el mejor rendimiento con aplicación de auxina. El enraizamiento de estacas tuvo más éxito en C. bracteata que en T. floribunda. Aplicaciones de ANA entre 200 a 500 mg L-1 fueron más adecuados para la propagación de C. bracteata debido a los mayores porcentajes de enraizamiento y la producción de brotes. Para la propagación de T. floribunda, se recomienda el uso de estacas apicales sin la aplicación de auxinas. Las raíces adventicias en estacas de ambas especies se originaron a partir de células del parénquima del tallo.
