Abstract: The arbuscular mycorrhizal status of 32 wetland plant species came from 15 families sampled in Kunming, Chengjiang, Jianshui, Tonghai, Shiping, Dongchuan and Luquan was surveryed by means of acid fuchsin stain after the roots were lysised in alkaline solution. Typical arbuscular mycorrhizal structures were detected in the roots of 11 species . Sixteen arbuscular mycorrhizal fungi belonging to 4 genera were wet-sieved from the rhizospheric soil of the wetland plants. Acaulospora and Glomus presented dominantly in the wetland soil (94% ). Glomus mosseae was dominant species in wetland soil and accounted for 88% of the total spores.
