Seasonal Diversity of Arbuscular Mycorrhizal Fungi in Mangroves of Goa, India

摘要

Seasonal dynamics of arbuscular mycorrhizal (AM) fungal community composition in three common mangrove plant species, namely,Acanthus ilicifolius, Excoecaria agallocha,andRhizophora mucronata,from two sites in Goa, India, were investigated. In all three species variation in AM fungal spore density was observed. Maximum spore density and AM species richness were recorded in the premonsoon season, while minimum spore density and richness were observed during monsoon season at both sites. A total of 11 AM fungal species representing five genera were recorded.Acaulospora laeviswas recorded in all seasons at both sites. Multivariate analysis revealed that season and host coaffected AM spore density and species richness with the former having greater influence than the latter.
