Differential diversity of Glomeromycota in relation to host species in the rhizosphere of native bromeliads from Sierra de las Quijadas National Park (San Luis, Argentina). Arbuscular mycorrhizal fungi (AMF) are associated with most of the plants, forming arbuscular mycorrhizas. Bromeliaceae is an American family living from the tropics to temperate and arid zones. Sierra de las Quijadas has species of terrestrial Bromeliaceae colonized by AMF with different degree of association. The aim of this work was to study the AMF spore diversity (richness and density) in the rhizospheric soil of three native species of Bromeliaceae from Sierra de las Quijadas. Richness and density of spores differed significantly between the Bromeliaceae species studied, with the lowest values in Bromelia urbaniana. Meanwhile, Deuterocohnia longipetala and Dyckia floribunda showed the highest values and only differed between them in richness of spores. This AMF differential diversity between the three bromeliads species may be related to the host species and also due to different levels of root colonization that were previously reported. Moreover, the low richness and density of AMF in the rhizosphere of B. urbaniana may be either due to anallelopathic effect of this plant or due to its particular root morphology. Resumen: Los hongos micorrícicos arbusculares (HMA) forman con la mayoría de las plantas asociaciones simbióticas denominadas micorrizas arbusculares. Bromeliaceae es una familia americana que habita desde los trópicos hasta zonas templadas y áridas. En el Parque Nacional Sierra de las Quijadas (San Luis, Argentina) las especies terrestres de Bromeliaceae están colonizadas por HMA, presentando distintos grados de asociación. El objetivo de este trabajo fue estudiar la diversidad (riqueza y densidad) de esporas de HMA en el suelo rizosférico de tres especies nativas de Bromeliaceae del Parque Nacional Sierra de las Quijadas. Riqueza y densidad de esporas difirieron significativamente entre las especies de Bromeliaceae estudiadas, siendo siempre marcadamente menores los valores obtenidos en Bromelia urbaniana, mientras que Deuterocohnia longipetala y Dyckia floribunda presentaron los mayores valores y sólo difirieron entre sí en la riqueza de HMA. Esta diversidad diferencial de esporas de HMA observada, podría tener relación conla especie hospedante y a su vez, con los distintos grados de colonización radical de cada especie que fueron descriptos en trabajos anteriores. Además, la escasa riqueza y densidad de esporas de HMA en B. urbaniana podría deberse tanto a un efecto alelopático de esta planta como a su particular morfología radical.

Differential diversity of Glomeromycota in relation to host species in the rhizosphere of native bromeliads from Sierra de las Quijadas National Park (San Luis, Argentina). Arbuscular mycorrhizal fungi (AMF) are associated with most of the plants, forming arbuscular mycorrhizas. Bromeliaceae is an American family living from the tropics to temperate and arid zones. Sierra de las Quijadas has species of terrestrial Bromeliaceae colonized by AMF with different degree of association. The aim of this work was to study the AMF spore diversity (richness and density) in the rhizospheric soil of three native species of Bromeliaceae from Sierra de las Quijadas. Richness and density of spores differed significantly between the Bromeliaceae species studied, with the lowest values in Bromelia urbaniana. Meanwhile, Deuterocohnia longipetala and Dyckia floribunda showed the highest values and only differed between them in richness of spores. This AMF differential diversity between the three bromeliads species may be related to the host species and also due to different levels of root colonization that were previously reported. Moreover, the low richness and density of AMF in the rhizosphere of B. urbaniana may be either due to anallelopathic effect of this plant or due to its particular root morphology. |
