Resumo: | The use of growth regulators or phytoregulators, is an alternative to increase flowering in the Pinaceae family. In this study, we examined the effects of the application of growth regulators (plant growth regulators) on vegetative shoots and male strobili of Pinus pinea L. Selected phytohormones were gibberellic acid (GA4/7), naphthalenacetic acid (NAA) and benzylaminopurine (BAP), combined in seven treatments, including control. These regulators were used in a 16 year-old plantation of Pinus pinea, located in Toconey, Pencahue, region of Maule-Chile. The treatments were applied in five dates (August to November). At the end of the applications, the following variables were evaluated: male flowering, number of vegetative buds and new buds and apical shoot length. The main results indicate that treatment T1 (GA4/7), is the most significant one on the male flower, showing a 99,6% increase in catkins regarding control branches, and it also had a significant effect on the length of apical buds, more than doubling the length of control. The number of vegetative buds, application of 500 mg L-1 showed significant differences BAP, obtaining an increase of 414.3% compared to the control treatment. |

En este estudio se analizaron los efectos de la aplicación de reguladores de crecimiento (fitorreguladores) sobre brotes vegetativos y estróbilos masculinos de Pinus pinea L. Los productos seleccionados fueron: giberelina cuatro más siete (GA4+7), ácido naftalenacético (NAA) y bencilaminopurina (BAP), distribuidos en siete tratamientos, incluido el control. Estos fitorreguladores se emplearon en una plantación de Pinus pinea de 16 años de edad ubicada en Toconey, comuna de Pencahue, región del Maule-Chile. Los tratamientos se aplicaron en cinco fechas, cada dos semanas (fin de agosto a inicio de noviembre). Al final de las aplicaciones se evaluaron las variables: estróbilos masculinos, número de brotes vegetativos y de nuevas brotes, y longitud de brotes apicales. Los principales resultados indicaron que la aplicación de 1.000 mg L-1 de GA4+7, fue el tratamiento que indujo la mayor floración masculina, presentando un 99,6 % más de estróbilos con respecto a las ramas testigo y también tuvo un efecto significativo en la longitud de los brotes apicales, aumentando más del doble la longitud respecto al testigo. En el número de brotes vegetativos, la aplicación de 500 mg L-1 BAP mostró diferencias significativas, obteniendo un incremento de 414,3 % con respecto al tratamiento control.La utilización de reguladores de crecimiento o fitorreguladores, es una alternativa para aumentar la floración en la familia Pinaceae.
