Histochemical changes in nodules of Cajanus cajan (L.) Mill sp. inoculated with vesicular- Arbuscular Mycorrhizal Fungus and Rhizobium

Abstract

Symbiosis of Glomus fasciculatum (Thaxter sensu Gerd) and Trappe, Rhizobium and Ca/anus cajan (L.) Millsp. was studied in relation with bacteroidal zone and polysaccharide accumulation in nodule tissue. Tripartite symbiosis enhanced the area of bacteroidal zone in nodule tissue and size of bacteroidal cell and nucleus. Association of vesicular-arbuscular rnycorrhizal fungus alone had maximum polysaccharide accumulation in the nodule tissue. Dual inoculation with rnicrosymbionts showed very little polysaccharide accumulation
