Assessment of arbuscular mycorrhizal fungi in the rhizosphere of Cedrela montana along an Andean elevational gradient
Rhizosphere soil samples were taken from individuals of Cedrela montana along an elevational gradient in the northern Andes. The abundance of spores and the frequency of infection by arbuscular mycorrhizal fungi (AMF) were analyzed considering the elevation and edaphic factors. The spores extraction...

| description | Rhizosphere soil samples were taken from individuals of Cedrela montana along an elevational gradient in the northern Andes. The abundance of spores and the frequency of infection by arbuscular mycorrhizal fungi (AMF) were analyzed considering the elevation and edaphic factors. The spores extraction was determined by the sieving technique and their count by stereoscopy; the frequency of infection, by clarifying with KOH and staining with trypan blue. The abundance of spores was positively correlated with the elevation of the study sites, while the frequency of rootlet colonization was not affected by elevation. Spore abundance was marginally affected by edaphic factors. On the contrary, mycorrhization by hyphae, vesicles and arbuscles showed an important influence of edaphic conditions, highlighting P, K and pH, and where elevation continues to be an important factor. |

Se analizó la abundancia de esporas y la frecuencia de infección por hongos micorrízicos arbusculares (HMA) considerando la elevación y factores edáficos. La extracción de esporas se determinó por la técnica de tamizado y el conteo de las mismas por estereoscopía; la frecuencia de infección, mediante clarificación con KOH y tinción con azul tripano. La abundancia de esporas se correlacionó positivamente con la elevación de los sitios de estudio, mientras que la frecuencia de la colonización de raicillas no se vió afectada por la elevación. La abundancia de esporas se vió marginalmente afectada por los factores edáficos. Por el contrario, la micorrización por hifas, vesículas y arbúsculos mostró una importante influencia de las variables edáficas, destacando P, K y pH, y en donde la elevación sigue siendo un factor importante.Ingeniero/a Biomédico/aUniversidad de Investigación de Tecnología Experimental YachaySandoya Sánchez, Carmen Verónica2022-09-19T13:52:20Z2022-09-19T13:52:20Z2022-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesishttp://repositorio.yachaytech.edu.ec/handle/123456789/569engrestrictedAccessinfo:eu-repo/semantics/openAccessreponame:Repositorio Universidad Yachay Techinstname:Universidad Yachay Techinstacron:Yachay2024-04-24T14:25:45Zoai:repositorio.yachaytech.edu.ec:123456789/569Institucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oaiEcuador...opendoar:102842024-04-24T14:25:45falseInstitucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oai.Ecuador...opendoar:102842024-04-24T14:25:45Repositorio Universidad Yachay Tech - Universidad Yachay Techfalse |
