| Abstract: | In a greenhouse pot experiment, maize was grown inoculated with the spores of the VAM fungi Glomus mosseae and Glomas multicaulis or non‐inoculated. Low soluble ferrous phosphate (FePO4.4H2O) was added to the mycorrhized and non‐mycorrhized maize. The fresh and dry weights of mycorrhized plants with added phosphate (P) were higher than in mycorrhized plants without added P or non‐mycorrhized plants with added P. The amount of P in the soil samples from pots with mycorrhizal plants fertilized with P was evidently smaller than those in samples also fertilized non‐mycorrhizal plants. The percentage of P was higher in tissues of fertilized mycorrhizal plants than in those mycorrhized plants without or non‐mycorrhized plants with added low‐ soluble P. These results indicated that plants in VAM symbiosis mobilize P better from low‐soluble P than non‐mycorrhized plants. |
