[Objective] Demonstrate the effects of arbuscular mycorrhiza(AM) fungi on Car-thamus tinctorius L.rhizosphere microbe diversity.[Methods] Dilution cultural and PCR-single stand conformational polymorphism(SSCP) were used for determing rhizosphere microbe exist in the ambient of inoculated AM fungi plants Carthamus tinctorius L.or named safflower as well.Target safflowers were inoculated with Glomus mosseae,G.intraradices and mixed group(G.mosseae,G.intraradices,G.cladoideum,G.microagregatum,G.caledonium and...
