Abstract
Algunos microbios beneficiosos del suelo ayudan al establecimiento y crecimiento de plantas medicinales exóticas. Evaluamos la
presencia y el estado de la asociación de endófitos de raíces
[hongos micorrízicos arbusculares (AM) y hongos endofíticos septados oscuros (DSE)] en diez especies de plantas medicinales
exóticas cultivadas en Nilgiris (Ghats Occidentales). Los hongos
AM colonizaron todas las especies examinadas y ocho plantas tuvieron la co-ocurrencia de hongos DSE. El alcance de las variables
de los hongos endofíticos y las características del pelo radicular difirieron significativamente entre las plantas. Se identificaron seis
morfotipos de esporas de hongos AM. Por lo tanto, este estudio
indicó la asociación de plantas medicinales exóticas con hongos
nativos AM y DSE que podrían explotarse para promover el crecimiento y aumentar la producción de metabolitos secundarios en
estas especies de plantas.
Some soil beneficial microbes help in the establishment and growth of exotic medicinal plants. We evaluated the presence and status of root endophyte [arbuscular mycorrhizal (AM) fungi and dark septate endophytic (DSE) fungi] association in ten exotic medicinal plant species cultivated in the Nilgiris (Western Ghats). The AM fungi colonized all the examined plant species, and eight plants had the co-occurrence of DSE fungi. The extent of fungal endophyte variables and root hair characteristics significantly differed among the plants. Six AM fungal spore morphotypes were identified. Thus, this study indicated the association of exotic medicinal plants with native AM and DSE fungi which could be exploited to promote growth and increase secondary metabolite production in these plant species.
