INTERACTION Between A VESICULAR–ARBUSCULAR MYCORRHIZAL FUNGUS AND STREPTOMYCES CINNAMOMEOUS AND THEIR EFFECTS ON FINGER MILLET

Abstract

Growth and phosphorus nutrition of finger millet (Eleusine coracana) on a sterile, phosphorus‐deficient soil was improved by inoculation with either the vesicular‐arbuscular mycorrhizal fungus Glomus fasciculatus or with the streptomycete Streptomyces cinnamomeous. These micro‐organisms interacted antagonistically when added simultaneously or with one 2 weeks after the other: Streptomyces reduced spore production and development of infection by Glomus, while Glomus reduced the multiplication of Streptomyces. Because of this antagonism, dual inoculations stimulated plant growth less than individual inoculations. Copyright © 1982, Wiley Blackwell. All rights reserved
