| dc.description | Forest plantations of Alder (Alnus acuminata), Laurel (Cordia alliodora), Melina (Gmelina arborea), Pine (Pinus radiata) and Teak (Tectona grandis) in Ecuador have the objective of producing quality wood (free of knots). Pruning is a key activity to meet this objective, and its implementation should be analyzed from the beginning of the establishment of the plantation. In general, the main pruning activity is formation pruning or low commercial pruning, followed by high pruning, defining the technical requirements: timing (defined by the diameter over the stump ¨between 14-15 cm¨, if these values are exceeded, it complicates the work and limits the production of clear wood), the technique to be used (orientation pruning ¨thin branches¨ and staggered pruning ¨thick branches¨), the intensity (moderate pruning allows a better balance between growth and stem diameter, the optimum being to prune no more than 25%) and the amount of pruning (always depending on the natural pruning and the characteristics of the leaf system of each forest species). At the same time, they have an effect on the variables (continuous "diameter on stump, diameter of cylinder with defects" and qualitative "sociological position of the tree, damage to the trunk, quality of the tree and of the pruning") that indicate the quality of the treatment carried out. At the same time, the impact of pruning will be balanced with other management activities, especially thinning, which represents one of the actions based on the biological urgencies of the species | es_ES |

| dc.description.abstract | Las plantaciones forestales de Aliso (Alnus acuminata), Laurel (Cordia alliodora), Melina (Gmelina arborea), Pino (Pinus radiata) y Teca (Tectona grandis) en el Ecuador tienen por objetivo la producción de madera de calidad (libre de nudos). La poda es una actividad clave para cumplir con dicho objetivo, y para su ejecución esta debe de analizarse desde el inicio del establecimiento de la plantación. Por lo general, principalmente se suelen realizar podas de formación o poda comercial tipo baja, seguida de la poda alta, definiendo los requisitos técnicos: momento oportuno (definido por el diámetro sobre muñón ¨entre 14-15 cm¨, si se superan estos valores, se complica la labor y se limita la producción de madera clara), la técnica a emplear (poda de orientación ¨ramas delgadas¨ y poda escalonada ¨ramas gruesas¨), la intensidad (podas moderadas permiten un mejor balance entre el crecimiento y el diámetro del fuste, siendo lo óptimo podar no más del 25%) y la cantidad de podas (dependiendo siempre de la poda natural y las características del sistema foliar de cada especie forestal). A su vez, que tienen efecto sobre las variables (continuas ¨diámetro sobre muñón, diámetro de cilindro con defectos ¨ y cualitativas ¨posición sociológica del árbol, daños en el fuste, calidad del árbol y de la poda¨) que nos señalan la calidad del tratamiento realizado. Al mismo tiempo, el impacto de la poda, será equilibrado con otras actividades de manejo, destacando el raleo, que representa un de las acciones basadas en las urgencias biológicas de las especies. | es_ES |
