[Primary research on arbuscular mycorrhizal fungi in rhizosphere of Chaenomeles speciosa in Xuancheng].

OBJECTIVE: To investigate the arbuscular mycorrhizal (AM) fungi resources in rhizosphere of Chaenomeles speciosa in Xuancheng, Anhui province. METHOD: Roots were stained with acid fuchsin and then mounted and observed under a microscope; Spores were extracted from the rhizosphere soil using wet-sieving method. RESULT: C. speciosa could be colonized and formed typical arbuscular mycorrhizas with AM fingi. 18 species of arbuscular mycorrhizal fungi were identified, belonging to four genera, 11 species of Glomus, 3 species of Acaulospora, 3 species of Scutellospora and 1 species of Entrophospora. Glomus were the dominant AM fungi in the rhizosphere. CONCLUSION: The resources of AM fungi in rhiszophere of C. speciosa were very abundant. Fungi from Glomus were possible the dominant AMF in the rhizosphere.
