Abstract:
Introduction: Arbuscular mycorrhizal (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 community of AM fungus species in the rhizospere may vary with host species (McGonigle and Fitter 1990). AM fungal trap cultures can be very helpful in unveiling fungal community members that are undetected in initial extraction spores from field soil (Morton et al. 1995). Although many AM fungi are thought to have a broad host range, the appropriate test plants for trap cultures should be evaluated to ensure maximum detection of fungal species in specific soils or site types. Gool: The primary purpose of this investigation was to evaluate natural plants root and silverweed cinquefoil as trap plants under pot-culture condition for detecting the presence of species of AM fungi. 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 “Shajin Khur” of Bogdkhan mountain. Research work to study AMF in root was performed there. Roots were washed with tap water, cut into 0.5-1.0 cm segments, cleared in 5% KON and stained with acid fucshin. Mycorrhizal colonization percentage was determined (Biermann and Linderman 1981). Analysis of variance was applied to spore and species numbers, and the colonization rate and means were compared by Duncan’s Multiple Range Test, . Results: Soil samples were taken from investigatory 6 points in variety environmental ranges such as larch forest, larch forest edge, mountain slope, wetlands, steppe and winter camp around “Shajin Khur” of Bogdkhan mountain. Research work to study AMF in root was performed there. And colonization rate of AMF in 34 species, 23 genera and 15 families. I did the research work at laboratory of Department of Botany, School of Biology, Inner Mongolia University. When the research work was done in according to method, there is following results. Hereto: versicular 16.4% and hyphae 39.1% in root contained in mountain slope soil versicular 14.3% and hyphae 54.4% in larch forest edge soil, versicular 8.1% and hyphae 61% in larch forest soil, versicular 24% and hyphaе 42.4% in steppe soil, versicular 21.3% and hyphae 50% wetlands soil, 6.1% and hyphae 55.1% in winter camp soil. Versicular and hyphae rate contained in root is showed in following table Conclusion: Studying AMF (Arbuscular mycorrhizal fungi) colonization in root is very important. Fungal symbioses in root are detected by the research work. Root and fungal symbioses are beneficial mutual. Plants have ability to adapt in various condition of ecology and AMF is very important factor for rehabilitation ecology. Thus I did AMF in roots.
