| description | Background: A rapid production of tree seedlings in nurseries with a high survival rate after transplanting is important to respond to the current demand for programs of restoration of arid environments by forestation. The low level of seedlings’ survival and establishment, caused by low moisture and nutrient content of soils, has been a bottleneck to reaching the target of the forest national restoration in Ethiopia of last years. It is suggested that, inoculation with root-associated plant growth promoting microorganisms could help to ameliorate this scenario and also respond to the Ethiopia's Green Legacy Program. Objective: To assess the potential of inoculation with
arbuscular mycorrhizal fungi (AMF) native to Ethiopia to improve the survival and growth of trees that could be used in afforestation programs in Ethiopia. Methodology: The study was carried out in three stages: (1) soil samples associated with roots of selected acacia species (T1-AMF of A. abyssinica, T2-AMF of A. seyal, T3-AMF of A. tortilis and T4-Control) were collected of highland and lowland areas from Ethiopia, (2) Sorghum (Sorghum bicolor (L.), provided by the Melkasa Agricultural Research Center-(MARC) served as a trap plant for the AMF consortium multiplication and (3) plant growth promotion by AMF was assessed throughout inoculations of seedlings of Delonix regia (Hook.) Raf., Sesbania grandiflora (L.), Cassia fistula L., and Azadirachta indica A. Juss., trees. Results: All inoculated seedlings showed significantly greater responses in all growth and mycorrhizal parameters over the non-inoculated trees. Consortium T2-AMF associated to roots of A. seyal from lowlands of Batu, showed significantly greater responses in all plant growth and mycorrhizal parameters over the AMF inoculums associated to other tree species evaluated. Significant and positive correlations were found between mycorrhizae and plant-growth parameters. Implications: Our results suggest that inoculation with native arbuscular mycorrhizal fungi indigenous from Ethiopia has the potential to significantly enhance survival and growth rates of tree seedlings. This could thereby advance national reforestation goals and addressing challenges in seedling establishment in arid environments. Conclusion: The potential for growth promotion and establishment of tree seedlings evidenced, implies that further efforts should be directed towards the in-mass production of AMF-based inoculants, particularly associated with A. seyal roots. |

Antecedentes: Una producción rápida de plántulas de árboles en viveros con una alta tasa de supervivencia tras el trasplante es importante para responder a la demanda actual de programas de restauración de ambientes áridos por forestación. El bajo nivel de supervivencia y establecimiento de las plántulas, causado por el bajo contenido de humedad y nutrientes de los suelos, ha sido el factor limitante para alcanzar el objetivo de la restauración forestal nacional en Etiopía de los últimos años. Se sugiere que la inoculación con microorganismos promotores de crecimiento vegetal asociados a las raíces de las plantas, podría contribuir a mejorar esta situación y también responder al Programa Legado Verde de Etiopía. Objetivo: Evaluar el potencial de la inoculación con hongos micorrícicos arbusculares (AMF) nativos de Etiopía, para mejorar la supervivencia y el crecimiento de plántulas que podrían ser utilizadas en programas de forestación en Etiopía. Metodología: El estudio se llevó a cabo en tres etapas: (1) colecta de muestras de suelo asociadas a raíces de acacia (T1-AMF de A. abyssinica, T2-AMF de A. seyal, T3-AMF de A. tortilis y T4-Control) de zonas de tierras altas y bajas de Etiopia, (2) multiplicación de consorcios de AMF nativos en raíces de sorgo (Sorghum bicolor L.), proporcionado por el Centro de Investigación Agrícola de Melkasa (MARC), como planta trampa, y (3) evaluación de la promoción del crecimiento en plántulas de Delonix regia (Hook.) Raf, Sesbania grandiflora (L.), Cassia fistula L. y Azadirachta indica A. Juss., por la inoculación con los consorcios con AMF. Resultados: Todas las plántulas inoculadas mostraron respuestas significativamente mayores en todos los parámetros de crecimiento y micorrización que las no inoculadas. El consorcio T2-AMF asociado a raíces de A. seyal autóctono de tierras bajas de Batu, mostró respuestas significativamente mayores en todos los parámetros de crecimiento y micorrización de las plantas, que los inóculos asociados a otras especies arbóreas evaluadas. Se encontraron correlaciones significativas y positivas entre los parámetros de micorrización y crecimiento de las plantas. Implicaciones: Nuestros resultados sugieren que la inoculación con hongos micorrícicos arbusculares autóctonos de Etiopía tiene el potencial de mejorar significativamente las tasas de supervivencia y crecimiento de las plántulas de árboles. De este modo se podría avanzar en los objetivos nacionales de reforestación, y hacer frente a los retos que plantea el establecimiento de plántulas en entornos áridos. Conclusiones: El potencial para la promoción del crecimiento y el establecimiento de plántulas de árboles evidenciado, implica que los futuros esfuerzos se deben dirigir hacia la producción en masa de inoculantes basados en AMF, particularmente asociados a las raíces de A. seyal.
