Abstract

Although members of the Oxalidaceae family have been described as host plants of vesicular-arbuscular mycorrhizal fungi, Oxalis pes-caprae did not become colonized by Glomus mosseae. Extracts of Ox. pes-caprae root inhibited the germination of G. mosseae spores. However, the presence of G. mosseae in the rhizosphere of Ox. pes-caprae produced browning of the roots, which was interpreted as a hypersensitivity response of the plant to the presence of VA fungus.
