[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.
