I inoculated two species of VA mycorrhizal fungi both separately and together, using different quantities of inocula in a soil with different quantities of lime added. I used Acaulospora leavis because germination of spores of this fungus has been shown to be decreased by increasing soil pH. I used Glomus sp. because in earlier studies infection by this fungus was not affected by pH. When the two species were inoculated together, I also studied the effect on root colonization by varying the placement of inoculum of Glomus sp. Adding lime increased soil pH, which decreased mycorrhizal formation by A. laevis when inoculated alone but infection by Glomus sp. was largely unafected. A. laevis colonized the greatest percentage of the roots in an acid soil (pH 4.7,1/5 w/v 0.01 M CaCl2) while Glomus sp. colonized most of the roots in a neutral soil (pH 7.3) when both fungi were inoculated together. The method of placement of inoculum of Glomus sp. did not affect root colonization by A.laevis. However, in an acid soil, Glomus sp colonized more roots in the presence of A. laevis when inoculum of Glomus sp. was banded than when inoculum was mixed throughout the soil; the reverse occurred in a neutral soil. I concluded that mycorrhizal formation by each fungus depended on the quantity of infective hyphae that reached the roots at an early stage of plant growth. In this study, the effect of one species upon another was associated with the amount of infection formed by each fungus at an early stage, that is, the higher the ...
