Abstract: The present study was to analyse the mycorrhizal diversity in AM fungi associated with 12 plants of J. P. University Campus, Chapra. Arbuscular mycorrhizal fungal colonization ranged from 44.4 – 100 % . The highest infection was found in Parthenium hysterophorus L. and lowest in Ricinus communis L . AM fungal spore population with a range of 10 – 155 in 100 g of rhizosphere soils was detected. The maximum spore population was observed in the species , Clerodendrum infortunatum Linn. ( 155/ 100 gm of soil) and minimum in Citrus lemon (L.) ( 10/ 100 gm of soil). A total of 25 AM fungal species were isolated which belongs to five genera ( Acaulospora, Entrophospora, Glomus, Scutellospora and Sclerocystis ) and among them Glomus was dominant genera. The maximum species richness (SR) was recorded in Ricinus communis L. (13) while the lowest (2) appeared in Citrus lemon (L.) . The highest Shannon wiener diversity (H ) was recorded in Ricinus communis L. (2.036) and lowest H was recorded in Clerodendrum infortunatum Linn. ( 0.875). The maximal Simpson′s diversity index (D) was recorded in Ricinus communis L. (0.86) and minimal D was recorded in Citrus lemon (L.) ( 0.29). The maximum species evenness (EH ) was recorded Azadirachta indica A. (0.92) and minimum EH was recorded in Citrus lemon (L.) ( 0.63).
Keywords: Arbuscular mycorrhiza, Root colonization, Species richness, Shannon -Wiener index, Simpson 's diversity index, Species evenness.
