    • Abstract

       

      Occurrence of vesicular arbuscular mycorrhiza in five subtropical ponds, i.e., eutrophic (P1,P2 andP3), running water (P4), oligotrophic lake (P5) and marshy plant community (M) was studied. It was observed that the plants growing inP1,P5 andM habitats exhibited the vesicular mycorrhizal association, whereas the fungal association was lacking in plants ofP2,P3 andP4 ponds. The endogonaceous spore population was estimated from water and sediments of the different ponds and it, was found that endophytes in sediments are less in terrestrial habitats and completely absent from water samples. The bioassay studies revealed that plants without mycorrhizal association grew poorly and all the endophytes isolated could establish vesicular arbuscular mycorrhizal associations in pot cultures.
