| Abstract: | Arbuscular mycorrhizal fungi (AMF) play an important role in soil ecosystem, but currently AMF cannot be purely cultured, and can only be propagated by symbiosis with host plants. In order to research the effect of different host plants on the propagation of AMF, maize (Zea mays L.), sorghum (Sorghum bicolor (L.) Moench), ryegrass (Lolium perenne L.) and clover (Trifolium pratense L.) were selected as hosts to propagate Rhizophagus aggregatus and Claroideoglomus etunicatum, respectively. The colonization rate, spore density, and inoculum potential of AMF were measured on the 30th, 60th, 90th and 120th day after AMF inoculation. The results showed that the effects of different hosts on the propagation of AMF were different. The colonization rates of R. aggregatus and C. etunicatum from high to low were maize > sorghum > clover > ryegrass, and the order of spore density of R. aggregatus was maize> sorghum > ryegrass > clover, the order of spore density of C. etunicatum was sorghum > maize> clover > ryegrass. The propagation effect of the same host on different AMF was also different. The effect of maize and ryegrass on R. aggregatus was higher than that of C. etunicatum, but the effect of clover and sorghum on the propagation of C. etunicatum was higher than that of R. aggregatus. It was also found that the spore density of AMF was related to the colonization rate of AMF, and there was a significantly positive correlation. The results show that maize is the best host plant for R. aggregatus propagation and sorghum is the best host plant for C. etunicatum propagation. |
