AM Fungal Biodiversity of forty six medicinal plants present in Sanjay Gandhi National park was studied and the data is compiled in the table below

  1. All theplants studied showedAM colonization in their roots and spores in the rhizosphere soils.
  2. Trap Culturewas set up for someplants.Spore count was more in trap culture, but in successive trap cultures, the spore count reduced.
  3. Maximumrootcolonization was seen in Lantana camara ( 95%)in trap culture conditons and was minimum in Mangifera indica ( 25%).
  4. Maximumrootcolonization in field conditions was seen in Helianthus annus (91%) and minimum in Tridax procumbens 18% .
  5. Maximumsporedensity was observed in Dipcadi montanum (61 spores/10g) in natural field conditions and minimum in.Euphorbia tirrucalli (5 spores/10g).
  6. Maximumsporedensity in trap culture was observed in Lantana camara(91 spores/10g) and Stachytarpheta indica ( 92 spores/10g) .
  7. Glomus and Acualospora were the most dominant genera reported. Few species of Gigaspora and Scutellospora were also identified.
  8. Root colonizationand sporedensity do not seem to have direct correlation.
  9. Thefungal structures observed weremostly arbuscules Linear type & Coiled type arbuscules and H shaped Y shaped hyphae.Vesicles were also observed in some plants. Auxillary cells were observed wherever Gigaspora was isolated.
  10. Ericoid typeofMycorrhizae were observed in Tridax and Adhathoda.
  11. Seasamumplant showed maximum AM diversityi.e. Species richness.
  12. Other endophytes &dark septateendophytes were of common occurrence in most of the plants.
