Abstract:

The intra- or inter-species genetic diversity of 11 strain AMF from five host trees were studied by random amplified polymorphic DNA(RAPD). The genetic diversity among AMF species from different host plants were more abundant than from same host plants. The results showed that the genetic diversity is related to AMF species and host plants, whereas the efficacy of AMF species is higher than that of host plants; the same species AMF having same origination, there were different morphology and genetic divisions because of the choice of hosts and the menace of environment, which leaded to form different affinity between AMF and trees.

Key words: arbuscular mycorrhizal fungi(AMF), molecular genetic, RAPD, trees
