This study investigated the quantitative and qualitative arbuscular mycorrhizal fungal (AMF) association in wild plant species growing on their natural habitat and their occurrence at different depths in soil from non-cultivated and non-fertile land of Bettiahraj, Bettiah, Bihar, India. For the determination of the AMF spores present at different depths, soil samples were collected separately from four different depths (approximately 8, 15, 23 and 30 cm). A variety of spores were recovered from soils and root washings, mainly belonging to the genus Glomus. The largest number of spores was recovered at a depth of 15 cm, followed by 8, 23 and 30 cm, in that order. Of the 10 plant species screened for AMF infection, only 8 displayed it (Cyperus rotundus, Croton bonplandianum, Cynodon dactylon, Cassia tora, Scirpus articulatus, Lycorpersicon esculentum, Solanum, and Leonurus sibiraus). AMF infection was maximum in Cyperus rotundus (40%) and minimum in Croton bonplandianus (4%). The roots of Rumex dentatus and Pteris vittata showed a complete absence of root infection but spores were present. Five species of Glomus, namely G. fasciculatum, G. aggregatum, G. mosseae, G. constrictum and G. intraradices; two species of Acaulospora, namely A. tuberculata and A. laevis, and one unidentified spore each of Gigaspora and Sclerocystis were observed. The mycorrhizal infection consisted of hyphae, vesicles and arbuscules. Glomus species were widespread in the non-cultivated soils. Tabulated data are included showing the population of AMF spores at different depths in soil collected from various spots of non-cultivated land, and AMF infection in roots of different wild plant species growing in their natural habitat.. |
