Mongolian Pharmacy and Pharmacology 2013;2(1):40-
Introduction: Arbuscularmycorrhizal (AM) fungi inhabit various ecosystems with a wide range of host plant species. However, as these funge are obligate symbionts with livings roots, the hosts play an important role in mycorrhizal development, spore formation and distribution of AM fungi. The communityof AM fungus species in the rhizospere may vary with host species (McGonigle and Fitter 1990). Whether the host can influence diversity of mycorrhizal fungi under controlled condition is an important issue as different researchers often use different test plants for studies on AM fungal diversity (Frank-Snyder et al. 2001; Helgason et al. 1998).Research main purpose is to study spores of arbuscularmycorrhizal fungi (AMF) and to classify spore types from soil.Materials and methods: Samples were collected from six diverse types of soil: larch forest, larch forest edge, mountain slope, wetlands, steppe and winter camp around “ShajinKhur” of Bogdkhanmountain.About 2 kg soil (2-20 cm) was collected from five randomly selected locations at each site. Soils at each sity were bulked, mixed and five replicate subsamples taken. Spores of AM fungi of each soil were extracted by wet- sieving from aliquots ((50 ml))and identified to species (Schenck and Perez 1988).Results: The soil sample was taken from the six sites such as Larch forest, Larch forest edge, Foot of mountain, washland, steppe, winter camp which are included to the natural various zone near “ShajinKhurkh” of Bogd Khan Mountain. By the survey the research team had found 26 species of spore to carry out survey on soil arbuscularmycorrhizal fungal (spore.The survey was carried out at the flora laboratory of “School of Biology” under the University of Inner Mongolia. We had the following result when the research work was done according to the research work methodology. Including:26 species of arbuscularmycorrhizal fungal (AMF) spore were determined from soil sample from the six sites near ShajinKhurkh of Bogd Khan Mountain, Acaulaspora 5species, Diversispora 3 species, Glomus 15 species, Entrophospora 1 species, Scutellospora 2 species. 16 species from Larch forest, 14 species from steppe, 12 species from washland, 11 species from Larch forest edge, 8 species from Graizing grassland, 7 species from mountain foot were determined. There is abundant spores of 4 AMF species such as Acaulaspora sp1, Acaulaspora sp3, Glomusambisporum, G.microaggregatum at 6 sites where the research sample was taken. Also there is abundant spore such as G.fasciculatum at larch forest, Glomusmosseae larch forest edge, Glomusclarum at washland, Glomus sp2 at graizing grassland, Entrophosporainfrenquens at steppe.Conclusion: The soil sample was taken from the six sites such as larch forest, larch forest edge, foot of mountain, washland, steppe, winter camp which are included to the natural various zone. In the result, 26 species, 5 genera of spore to carry out survey on soil arbuscularmycorrhizal fungal (AMF) spore were determined including Acaulaspora 5 species, Diversispora 3 species, Glomus15 species, Entrophospora 1 species, Scutellospora 2 species. There is abundant Glomus type spore.The research work is being implemented to continuedoing the AMF survey further.References1.
