Influence of Vesicular Arbuscular Mycorrhizae on the Growth of Apple and Corn in Low-Phosphorous Soil

Abstract

Growth responses of apple and corn plants to inoculation with Glomus mosseae were observed in a fumigated low P soil. Roots of these crops did not become infected after inoculation with G. microcarpus and no growth responses were observed. Corn was apparently protected from As toxicity by vesicular arbuscular (VA) mycorrhizae. Apple seedlings were more VA mycorrhiza-dependent than were corn plants in this study.
