The aim of the present research was to evaluate the effect of three vesicular arbuscular Mycorrhi al native genera application on growth of Hartón plantain plants in nursery stage. The strains were obtained at the Universidad de Córdoba from the Plant Pathology Laboratory collection, which were isolated from plantain crops in Lorica, Las Córdobas and  San Bernardo del Viento. A completely randomized experimental design with six treatments DTE was used: Glomus sp. T1, Acaullospora sp. T2, Scutellospora sp. T3, a genera combination of Glomus, Acaullospora and Scutellospora T4, a chemical treatment diammonium phosphate, DAP, T5E and absolute control DT6E, with ten replicates per treatment. Results showed that a greatest quantity of spores were obtained and higher infection percentage with the combination of mycorrhizae genera DT4E, followed by TY, T3 and T2 treatments. Besides the above mentioned, with the combination of mycorrhizal genera, they were obtained significant difference compared with other treatments in regard to pseudostem diameter, leaf area ratio:fresh and dry weight of root. Regarding to leave area and root length, T5 treatment showed the higher measurements., En el trabajo se evalúo el efecto de la aplicación de tres géneros nativos de micorrizas vesículo arbusculares sobre el crecimiento de plantas de plátano Hartón Musa AAB Simmonds en etapa de vivero. Las cepas se obtuvieron de la colección del Laboratorio de Fitopatología de la Universidad de Córdoba, las cuales fueron aisladas de cultivos de plátano en los municipios de Lorica, Los Córdobas y San Bernardo del Viento. Se utilizó el diseo experimental completamente al azar, con seis tratamientos T: Glomus sp. T1, Acaullospora sp. T2, Scutellospora sp. T3, una combinación de los géneros Glomus, Acaullospora y Scutellospora T4, un tratamiento químico de fosfato diamónico, DAP T5 y un control absoluto T6, con diez repeticiones por tratamiento. Los resultados mostraron que con la combinación de géneros de micorrizas T4 se obtuvo un mayor número de esporas y un porcentaje más alto de infección, seguido de los tratamientos T1, T3 y T2. Además, con esta combinación se encontraron diferencias significativas en diámetro del pseudotallo, relación de área foliar:peso fresco y seco de raíz, en comparación con los demás tratamientos. El área foliar y la longitud de raíz fueron más altos en el tratamiento T5.

The strains were obtained at Universidad de Córdoba from the Plant Pathology Laboratory collection, which were isolated from plantain crops in Lorica, Los Córdobas and San Bernardo del Viento.
A completely randomized experimental design with six treatments (T) was used: Glomus sp.
(T1), Acaullospora sp.
(T2), Scutellospora sp.
(T3), a genera combination of Glomus, Acaullospora and Scutellospora (T4), a chemical treatment (diammonium phosphate, DAP, T5) and absolute control (T6), with ten replicates per treatment.
Results showed that more spores and larger infection percentage were obtained with the combination of mycorrhizae genera (T4), followed by T1, T3 and T2 treatments.
Besides the above, with the combination of mycorrhizal genera, they were significantly different compared with other treatments in regard to pseudostem diameter, ratio of ...
