Arbuscular mycorrhizal fungal occurrence in non-cultivated disturbed and non-fertile land of Bettiahraj, Bettiah, Bihar

摘要

Arbuscular mycorrhizal fungi, or AMF, help in the conversion of non-fertile soils into fertile and productive soils. Such fungi are commonly found in soils deficient in nutrients, and may compete with bacteria, actinomycetes, and other fungi. The AMFalso help in transport and uptake of phosphorus, besides helping in plant growth and thereby in increasing biomass and yield. Infection by AMF of crop plants and forest trees leads to the spread of hyphae and formation of vesicles/arbuscules inside the root cortex of various host plants. In the present investigation, an attempt has been made to find the quantitative and qualitative AMF association in wild plant species growing in their natural habitat and their occurrence at different depths in soil from non-cultivated and non-fertile land of Bettiahraj, Bettiah, Bihar.
