Arbuscular Mycorrhizal Status of the Plants Growing in the Alkaline/Sodic Soils of Pratapgarh, Allahabad, Uttar Pradesh

Harbans Kaur Kehri*, Varun Khare, Pooja Rai, Pallavi Rai


In India approximately 7 mha land is salt affected out of which 2.5 mha occurs in Indo-Gangetic plains. In Uttar Pradesh alone about 1.29 mha is salt affected. In the present study a survey was made to investigate arbuscular mycorrhizal status of the wild plants growing in alkaline/sodic soils of Pratapgarh, Allahabad, Uttar Pradesh, so that the adoptive and effective AMF isolates may be used in further studies to give the solution for the reclamation and utilization of such soils. A total of 18 plant species belonging to 18 genera and 9 families were identified from different zones of the selected site. Cyperus rotundus L., Desmostachya sp., Saccharum munja Roxb., and Sporobolus diander (Retz.), P. Beauv. were the most dominant grasses in I to III zones. However, zone IV, where cultivation was being practiced, was mainly dominated by the cultivated crops. All the plants showed mycorrhizal association in their roots, except the member of Brassicaceae and Cyperaceae. A total of 19 species belonging to three genera of AM fungi were isolated. Glomus was recorded as the most dominant genus with 13 species.
