Flowers are highly demanded throughout the globe due to change in people’s life style and standard of living. In India
floriculture can contribute significantly in the economy if a technology is developed which may enhance the quality and production of flowers in an integrated way and ecofriendly manner that reduces the cost of cultivation. Knowing to the
importance of ornamental plants, five highly demanded ornamental plants were selected for the purpose of survey to
study the arbuscular mycorrhizal fungal diversity and trends of mycorrhization from seven different sites located in
Allahabad, Uttar Pradesh. All the species were found to be mycorrhizal but the extent varied with plants as well as sites. A total of 53 species belonging to four different genera of AM fungi were isolated as the most dominant forms
associated with the ornamental plants. Glomus was recorded as the most dominant genus with 31 species, followed by
Acaulospora with 16 species, Gigaspora with five species, Scutellospora with a single unidentified species. Shannon
Weiner diversity index, Simpson Index of Dominance, Species richness and Species evenness studies carried out in
these sites showed less variation in all the sites, exhibiting a stable and a diverse fungal community. Pearson correlation analysis indicated a positive correlation between spore density and organic carbon content while a negative
correlation was found between spore density and phosphorus value. |
