The Effect of Mycorrhiza on the Growth of Maize

Abstract

Mycorrhizal maize grew much larger than nonmycorrhizal maize in phosphorus deficient soils. Nonmycorrhizal plants exhibited phosphorus deficiency symptoms. Mycorrhizal plants contained a higher concentration of phosphorus, and soil analysis showed they had removed more phosphorus from the soil than nonmycorrhizal plants. The extent of mycorrhizal infection was correlated with increases in growth.
