Abstracts |
An extensive survey on the distribution of various arbuscular mycorrhizal fungi (AMF) in the rhizosphere of different soyabean cultivars (JS-335, JS71-05, NRC 2, NRC 7 and NRC 12) being grown in the Jabalpur region of Madhya Pradesh, India was conducted to study the AMF diversity in the soyabean cropping fields. Intense AM colonization wa restricted in the epidermal and cortical parenchymatous cells near the root bases. The roots exhibited a fairly good colonization characterized by the presence of hyphae, arbuscules and vesicles. Maximum number of AMF spores were recorded in the rhizosphere of NRC 2 cultivar while the least number of spores were recorded in the JS 335 cultivar. A total of 22 types of AMF spores belonging to Acaulospora (4 species), Glomus (10 species), Gigaspora (3 species), Scutellospora (2 species), Sclerocystis (2 species) and Entrophospora (1 species) were identified. Glomus, Acaulospora and Gigaspora were commonly found. Glomus was the most abundant genus of which Glomus intraradices was the most prevalent. |
