| 摘 要： | 用碱解离、酸性品红染色法对昆明、澄江、建水、通海、石屏、东川和禄劝等地的15个科32种湿地植物的丛枝菌根状况进行了调查，共发现有11种植物形成丛枝菌根，占34％。从湿地植物根际土壤中分离、鉴定出分属于4个属的丛枝菌根真菌共16种，无梗囊霉属（Acaulospora）和球囊霉属（Glomus）是湿地土壤中的优势类群（94％）。摩西球囊霉（G．mosseae）占孢子总数的88％，是湿地土壤中的优势种。

| 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. |
