| description | This paper attempts to present the state of the art in the knowledge of multiplication of woody species by nonsexual methods, given the need to obtain juvenile or rejuvenated material for the success of vegetative propagation or cloning. In fruit species, propagation by grafts on juvenile stocks is an effective method for partially rejuvenating adult material, or in other terms, mature material. In the course of the presentation, emphasis will be made on methods applicable to the mother plant as well as those used for in vitro culture.
In forest trees, research on this type of propagation has increased in the last few years; however, there are few instances of massive production of individuals. The advantages of this method are the possibility of achieving rapid multiplication of individuals (selected for their productivity, quality, resistance to pathogens, etc.), the cloning of hybrids and polyploid organisms by means of conventional techniques (grafting, rooting of cuttings, etc.) or by in vitro culture of meristems, tissues, or cells.

El trabajo está dedicado a presentar el estado actual del conocimiento en lo que se refiere a la multiplicación por métodos no sexuales de especies forestales, y a la necesidad de obtener material juvenil o rejuvenecido para lograr éxito en la propagación vegetativa o clonación. En las especies frutícolas es común la propagación por medio de injertos sobre porta-injertos juveniles, un método eficaz para rejuvenecer parcialmente material adulto o, en otros términos, maduro. Durante el desarrollo se hará hincapié tanto en métodos aplicables a la planta madre como en aquellos empleados en el cultivo in vitro. En los últimos años han tomado incremento las investigaciones sobre este tipo de propagación en varias especies forestales, aunque son escasas en las cuales exista producción masiva de individuos. Entre las ventajas que presenta su empleo se ubican la posibilidad de lograr un mejoramiento rápido de individuos seleccionados por su productividad, calidad, resistencia a patógenos, etc., por medio de técnicas convencionales (injertos, enraizamiento de estacas, acodos, etc.) o por el cultivo in vitro de meristemas, tejidos o células, además de permitir la clonación de híbridos e individuos poliploides.
