The mutual relationship between the plant and mycorrhizal fungi has opened a new area of research in the interest of plant health in adverse soil conditions. An investigation was carried out to record AMF diversity in the rhizosphere of different minor millets viz. Eleusine coracana, Panicum miliaceum and Paspalum scrobiculatum growing in the rainfed areas of Bihar and Jharkhand states, India. Pot experiments were conducted to evaluate the inoculation effect of mycorrhiza on plant growth performance at four different levels of phosphorus in soil. Results showed that mycorrhizal dependency of plant was always minimum at higher P concentration in soil, which indicated that additional phosphorus beyond 0.75 mg/100 g soil reduces the degree of mycorrhizal colonization vis a vis mycorrhizal dependency of plant. Low level of colonization in plants growing with high P-status is due to the specific signal from the plant regulating the activity of the fungus. It is suggested that mycorrhizal plant demand of phosphorus may regulate the activity of P transporter in the fungal partner. |
