Occurrence of AM fungi in Xanthium strumarium L.plants of Osmanabad District

A survey of the arbuscularmycorrhizal (AM) status associated with Xanthium strumariumL plants growing and distributed in Osmanabad district of Marathwada region in Maharashtra state. The result showed that all the different sites Xanthium strumarium L. plants had AM fungal association in the roots and spore population in the rhizosphere soil.
