Resumen

En la constante búsqueda de tecnologías que incrementen el enraizamiento en miniestacas de Eucalyptus spp, el uso de rizobacterias ha emergido como una alternativa viable. Las rizobacterias utilizan los exudados de la raíz de las plantas como fuente de carbono y nitrógeno y a su vez poseen diversos mecanismos que pueden promover el crecimiento de las plantas. Los resultados de esta investigación constataron que 12 cepas de rizobacterias promovieron simultáneamente el enraizamiento en ambos clones y 9 aumentaron la longitud de la raíz en al menos un clon; evidenciándose además una respuesta diferencial bacteria x clon.
