Con el objetivo de seleccionar e identificar los diferentes morfotipos de hongos micorrizicos arbusculares (HMA) nativos predominantes y determinar el porcentaje de colonización y densidad de esporas en suelos de la Subcuenca del Cumbaza asociados a plantas de cobertura, se seleccionaron suelos degradados de las localidades de Chirikyacu, Vista Alegre, El Chontal, San Antonio, Aucaloma, y Shapumba; donde se tomaron muestras de suelos y se asociaron a cuatro leguminosas de cobertura Cajanus cajan, Canavalia ensiformis, Crotalaria juncea y Vigna unguiculata. Se utilizó un diseño completamente al azar, con arreglo factorial de 6Ax4B,con tres repeticiones y a nivel de significancia de p<0,05, considerando el factor A (zona) y el factor B (leguminosa). Los resultados mostraron que las leguminosas tuvieron mayor influencia en cuanto al porcentaje de colonización micorrízica en comparació...

In order to select and identify the different morphotypes of predominant native arbuscular mycorrhizal fungi (AMH) and determine the percentage of colonization and spore density in soils of the Cumbaza subbasin associated to cover plants, degraded soils were selected from the localities of Chirikyacu, Vista Alegre, El Chontal, San Antonio, Aucaloma, and Shapumba; where soil samples were collected and associated with four legumes covering Cajanus cajan, Canavalia ensiformis, Crotalaria juncea and Vigna unguiculata. A completely randomized design with factorial arrangement of 6Ax4B was used, with three replications and at significance level of p <0.05, considering factor A (zone) and factor B (legume). The results showed that the legumes had a greater influence on the percentage of mycorrhizal colonization compared to the areas under study, with Vigna unguiculata having the highest percent...

Arbuscular mycorrhizal fungi (AMF) are organisms that form mutualistic associations with most plants, favoring their development, especially those located in degraded areas. In order to identify the different predominant native AMF morphotypes, and determine the percentage of colonization, and spore density in soils of the Cumbaza sub-basin in San Martin, Peru, soil samples were taken from degraded areas of Chirikyacu, Vista Alegre, El Chontal, San Antonio de Cumbaza, Aucaloma and Shapumba, and they were associated with 4 legumes cover crops among them, Cajanus cajan, Canavalia ensiformis, Crotalaria juncea and Vigna unguiculata. A completely random design was used, considering 6 zones and 4 legumes with 3 replications. The results showed that the treatments with legumes had greater influence in the mycorrhizal colonization in comparison with the zones of study, being Vigna unguiculata t...
