description Arbuscular mycorrhizal fungi presences in the rhizosphere of avocado trees with symptoms of root rot sadness caused by Phytophthora cinnamomi were determined. The investigation was done in the avocado orchard "Ojo de agua" in the town of Tancitaro, Michoacan, Mexico, in 21 previously selected trees. For the control of P. cinnamomi were applied three strains of Trichoderma (T. erinaceum, T. aggressivum and T. arundinaceum) before the application was made the first soil sampling, the second 6 months later, before the second application of Tricoderma strains and the last 12 months before the third application. To remove soil spores was used wet sieving and decantation protocol proposed by Gerdemann and Nicolson (1963), followed by centrifugation on sucrose (400 g L-1) at 2000 rpm. Taxonomic identification was based on the morphological characteristics of AMF spores, considering the shape, size and color, and thickness, ornamentations and number of the layers of the wall, coupling form and supporting hyphae, identifications were made by comparison with original descriptions available in the International Collection of Arbuscular Mycorrhizal Fungi and Glomeromycota species list. The first sampling were identified eleven species in seven genera: Glomus with two undetermined species, Glomus sp.1, Glomus sp.2, Glomus etunicatum and Glomus geosporum; genus Acaulospora, one undetermined species Acaulospora sp., A. spinosa, A. bireticulata and A. denticulate; genus Entrophospora, E. infrequens; genus Diversispora, D. aurantia; genus Scutellospora, S. pellucida; genus Racocetra, R. castanea and R. verrucosa and genus Gigaspora, Gi. decipiens. In the second and third sampling, the presence of new kinds of HMA there was not observed but the number of spores increased (average 38.09% and 30% respectively). The application of these species in the genus Trichoderma to control root pathogens of avocado encouraged the growth of HMA spores in the rhizosphere of the crop.

El trabajo se realizó en el huerto de aguacate “Ojo de agua” en el municipio de Tancítaro, Michoacán, México, en 21 árboles previamente seleccionados. Para el control de P. cinnamomi se aplicaron tres especies de Trichoderma (T. erinaceum, T. aggressivum y T. arundinaceum) el primer muestreo se realizó previo a la aplicación, el segundo 6 meses después, antes de la segunda aplicación y el último a los 12 meses, antes de la tercera aplicación. Para extraer las esporas del suelo se utilizó el protocolo de tamizado húmedo y decantación propuesto por Gerdemann y Nicolson (1963), seguido de centrifugación en sacarosa (400 gL-1) a 2000 rpm. La identificación taxonómica fue con base en las descripciones originales, que consideran la forma, tamaño y color de las esporas; grosor, número y ornamentación de las capas de la pared, así como forma y acoplamiento de la hifa de sostén, se hicieron las identificaciones por comparación con las descripciones originales propuestas en la International Collection of Arbuscular Mycorrhizal Fungi y la AMF phylogeny. Del primer muestreo se identificaron 11 especies incluidas en siete géneros: Glomus con dos especies no determinadas, Glomus sp.1, Glomus sp.2, Gl. etunicatum y Gl. geosporum; género Acaulospora, una especie no detrminada Acaulospora sp., A. spinosa, A. birreticulata y A. denticulata; del género Entrophospora, E. infrecuens; del género Diversispora, D. aurantia; del género Scutellospora, S. pellucida; del género Racocetra, R. castanea y R. verrucosa y del género Gigaspora; Gi. decipiens. En el segundo y tercer muestreo, no se observó la presencia de nuevos géneros de HMA pero si aumentó la cantidad de esporas (en promedio 38.09% y 30% respectivamente). La aplicación de estas especies del género Trichoderma para el control de fitopatógenos de la raíz de aguacate favoreció el incremento de esporas HMA en la rizosfera de este cultivo.Universidad Autónoma de YucatanScientific Research Council of the Universidad Michoacana de San Nicolas de Hidalgo, which financed this project.
