Se investigo el uso de la yuca como un hospedante alterno para la multiplicacion de hongos micorrizogenos vesiculo- arbusculares (MVA) para inoculacion masiva en el campo. En un primer ensayo con hongos MVA encontradas en medio de las capas de cascaras de raices de yuca, se registro una alta infeccion de los hongos MVA inoculados con cascaras de yuca; no se presentaron diferencias significativas entre los tratamientos de cascara de yuca sola y cascara de yuca + lechada de lignita, ambos a concn. de inoculo de 1 y 10 g/planta. En un segundo ensayo, se encontro que las cepas de hongos MVA aisladas de batata y name infectaron a la yuca de manera similar a la cepa de yuca. La respuesta de la yuca a una cepa de coleo fue comparativamente menor y un cultivo no nativo de Glomus mossae tambien logro infectar plantas de yuca en forma mas eficiente que la cepa nativa. El fenomeno de no especificidad de la yuca a varios hongos VA y la ocurrencia frecuente del hongo en las cascaras puede ser de utilidad en la multiplicacion masiva de cepas eficientes. (CIAT) spa
The use of cassava as an alternate host for the multiplication of vesicular-arbuscular mycorrhizae (VAM) fungi for mass inoculation in the field was investigated. In a 1st test with VAM fungi found embedded in between the layers of cassava root peels, high infection of the VAM fungi inoculated with cassava peels was recorded; there were no significant differences between the treatments cassava peeling alone and cassava peeling + lignite slurry, both at inoculum concn. of 1 and 10 g/plant. In a 2nd test, VAM strains isolated from sweet potatoes and yams were found to infect cassava in a similar way as the cassava strain. The response of cassava to a coleus strain was comparatively less, and a nonindigenous culture of Glomus mossae was also able to infect cassava plants more efficiently than the native strain. The phenomenon of nonspecificity of cassava to various VA fungi and the prevalence of the fungus in the peels can be of use in the mass multiplication of efficient strains. (CIAT) eng
