Dear Dr. Ahmad, I found in my archives two other papers, which can be helpful for your purpose. Hoping you will consider the papers I provided you interesting. Kind regards, Anicet Beauvais
Horst Vierheilig, Peter Schweiger, Mark Brundrett. 2005. An overview of methods for the detection and observation of arbuscular mycorrhizal fungi in roots. Physiologia Plantarum 125: 393–404.
Hope you have already got your answer. The easiest method is wet sieving and decanting method developed by Gerdemann and Nicolson in 1963, which I also used in my Ph D research.
