Two experiments were designed to investigate the effects of soil disturbance and organic P (Naphylate and lecithin) on mycorrhiza formation and symbiotic efficiency of AMF associated with maize in greenhouse. The results showed that P forms did no[ affect the root colonization of BEG167 and Glomus versifome (G.v,) with maize. G.v, produced more extraradical fungal biomass than BEG167 when KH2PO4 and lecithin were applied. The treatments with lecithin and KH2PO4 had higher maize biomass than those supplied with Na-phytate. BEG167 and G.v differed ill maize biomass contribution when Na-phylate was applied. Soil disturbance reduced significantly root colonization, and significantly or slightly decreased shoot biomass and 11 uptake of maize colonized by BEG141. However, mycorrhiza development and symbiotic efficiency of G.v were not influenced by soil disturbance. Oil cellulose acetate membrane. Numerous regeneration hyphae with anastomosis structure and dichotomous structure were observed. The results suggested that rapid recovery of extraradical hyphae of AMF might compensate the P contribution loss caused by soil disturbance and buffer the decrease of propagule reserve in soil ecosystem. |
