Ultra structures of nodules of cajanus cajan (L) mill sp. Inoculated with vesicular-arbuscular mycorrhizal (Vam) fungus

Abstract

Ultrastructural observations made on nodules of Cajanus cajan (L) Millsp. indicated that tha association of VA mycorrhizal fungus Glomus fasciculatum did not influence tha number of bacteroid formed per membrane envelop, which was always one. Both the transformed cell size and number of bacteroid/ Rhizobium pressnt in transformed cell were increased due to mycorrhizal association. Bacteroidal shape differed from the Rhizobium However, no such difference was noticed in size.
