| description | Rooted cuttings are an alternative for the massive cloning of selected trees, with desirable and superior traits for commercial plantations. However, rooting capacity diminishes rapidly at 2 or 3 years of age in conifer species. The aim of this work was to evaluate the rooting capacity of Pinus patula cuttings obtained from 15- and 18-months-old mother plants grown with different fertilization doses and growth conditions (management), with the application of 5000 × 10-6 (5000 ppm) of indole-3-butyric acid (IBA) in liquid solution or with the Radix® commercial product as paste. Fourteen weeks after establishing the rooting trial, survival, rooting, and callus formation were evaluated in cuttings, as well as the number and length of primary roots, and presence of secondary roots. Significant effects (p ≤ 0.05) were found on the evaluated factors and in their interaction. Application of IBA in solution for 10 s or 20 s caused the highest rooting percentage (> 25%), 2-3 times more than the control (8.5%). Fertilization of mother plants with 7 g L-1 Osmocote® under shade mesh caused high cutting mortality (30%). No differences were found in length of the longest root, nor in average length of primary roots. The combination of an 18-month-old mother plant fertilized with 5 g L-1 Osmocote® in the greenhouse, and the application of IBA in liquid solution for 20 s produced 73.8% rooted cuttings, an acceptable value in a Pinus patula cloning operational program. |

El enraizado de estacas es una alternativa para la clonación masiva de árboles seleccionados, con características deseables y superiores para plantaciones comerciales. Sin embargo, la capacidad de enraizado disminuye rápidamente a los 2 o 3 años de edad en especies de coníferas. El objetivo de este trabajo fue evaluar la capacidad de enraizamiento de estacas de plantas madre de Pinus patula de 15 y 18 meses de edad, con diferente dosis de fertilización y condición de crecimiento (manejo), y con la aplicación de 5000 × 10-6 (5000 ppm) de ácido indol-3-butírico (AIB) en solución líquida o con el producto comercial Radix® en pasta. A las 14 semanas de establecido el ensayo se evaluó el porcentaje de supervivencia, estacas con callo y raíces, así como el número, longitud de raíces primarias y presencia de raíces secundarias. Se encontraron efectos significativos (p ≤ 0.05) en los factores evaluados y en su interacción. La aplicación de AIB en solución durante 10 s o 20 s ocasionó el mayor porcentaje de enraizamiento (> 25%), 2-3 veces más que el testigo (8.5%). La fertilización de la planta madre con 7 g L-1 de Osmocote® bajo malla sombra provocó una mortalidad elevada de las estacas (30%). No se encontraron diferencias en longitud de raíz más larga, ni en longitud promedio de raíces primarias. La combinación de planta madre de 18 meses con fertilización de 5 g L-1 de Osmocote® en invernadero y la aplicación de AIB en solución líquida por 20 s produjo 73.8% de enraizado, valor aceptable en un programa operativo de clonación de Pinus patula.
