Arbuscular Mycorrhizae in association with aquatic and marshy plant species in Goa, India

Of the 20 plant species of hydrophytes screened for Arbuscular Mycorrhizal (AM) fungal root colonization, 10 aquatic plants (out of 14 species) and five marshy plants (out of six species) were found to be mycorrhizal, while the remaining species were non mycorrhizal. Vesicular colonization occurred in 12 plant species while arbuscular colonization was restricted to only three plant species. A rooted submerged pteridophyte viz., Isoetes coromandelina L. was found to be mycorrhizal exhibiting vesicular colonization. In all, two genera viz., Glomus and Scutellospora, the former being dominant, were recorded. The most common AM fungal species Glomus claroideum was recovered from 14 plant species.
