Item Histochemical changes in nodules of Cajanus cajan (L.) Mill sp. inoculated with vesicular- Arbuscular Mycorrhizal Fungus and Rhizobium(Kerala Agricultural University, 1988) Sivaprasad, P; Joshi, S S; Rai, P VSymbiosis 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 accumulationItem Ultra structures of nodules of cajanus cajan (L) mill sp. Inoculated with vesicular-arbuscular mycorrhizal (Vam) fungus(Kerala Agricultural University, 1988) Sivaprasad, P; Rai, V; Joshi, S SUltrastructural 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.
