Resumen

Las orquídeas (Orchidaceae) son uno de los grupos más diversos de plantas vasculares, gracias a su capacidad para formar asociaciones mutualistas con diversos microorganismos presentes en sus raíces. Este estudio tuvo como objetivo aislar e identificar taxonómicamente hongos y bacterias asociados a las raíces de cinco especies de orquídeas epífitas del sur de Ecuador: Stelis superbiens Lindl., Cyrtochilum myanthum (Lindl.) Kraenz, Masdevallia rosea Lindl., Epidendrum rhopalostele Hágsater & Dodson y Cyrtochilum flexuosum Kunth. Se recolectaron un total de 52 muestras en dos lugares del sur de Ecuador. Se obtuvieron 17 aislados fúngicos, pertenecientes a las familias Dermateaceae, Aspergillaceae, Herpotrichiellaceae, Nectriaceae y Polyporaceae. Además, se aislaron seis bacterias de las familias Pseudomonadaceae, Burkholderiaceae y Comamonadaceae. Los resultados aportan información sobre la diversidad de microorganismos asociados a las raíces de las especies estudiadas y pueden servir de base para futuras investigaciones sobre sus interacciones ecológicas y su posible aplicación en programas de conservación de orquídeas.
