Abstract:
All the plants in an area upto 15m around the hot water spring were found to be mycorrhizal except Amaranthus viridis. The spectrum of species composition and the status of VA infection both changed considerably in relation to distance from the spring. In the first 5m zone, adjacent to the spring, VAM colonization was very poor as compared to the same or different species in the next zone at 5m distance from the spring and it further improved in the farthest zone of 10 m from the spring. The percentage of mycorrhizal colonization appears to be directly related to the levels of SO4- content in various zones. Five endophyte species, 4 belonging to the genus Glomus and one to Acaulospora were identified from S-rich soils. Of these G. fasciculatum was relatively more prevalent, hence appears be more tolerant as compared to G. mosseae which made its appearance only in the III zone of low SO4-content.
