On the Diversity of Rhizosphere Arbuscular Mycorrhizal Fungi of Guizhou Endemic Medicinal Plants

The diversity of medicinal plant rhizosphere arbuscular mycorrhizal fungi(arbuscular mycorrhizal fungi, AMF) in Guizhou Province is studied by T-RFLP method experiment. The results show that: the rhizosphere AMF of four kinds of medicinal plants in Guizhou Province is varied and the number is large. Different plant species, AMF diversity is quite different, which proves the effects of host plants on rhizosphere microbial community structure diversity; at the same time, organic matter, p H and available phosphorus have greater impact on the rhizosphere AMF diversity.
