10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 3 2012 (July - September) Earthen pot experiments were conducted in a randomized block design with three replications to evaluate the effects of Tomato ( lessThan i greaterThan Solanum lycopersicum lessThan /i greaterThan L.) varieties, PMK-1 and Vaibhav. The indigenous species; lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan (Thaxter) Gerdmann and Trappe emend. Walker & Koske, lessThan i greaterThan Gigaspora margarita lessThan /i greaterThan Becker & Koske, lessThan i greaterThan Sclerocystis dussii lessThan /i greaterThan (Patouillard) von Hohnel, and lessThan i greaterThan Acaulospora laevis lessThan /i greaterThan Gerd & Trappe., were used in the study species Sorghum was used as a trap host. All species had the ability to colonize tomato root with different colonization levels. Significantly higher root were colonized by lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan compared to lessThan i greaterThan Acaulospora laevis. lessThan /i greaterThan A lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan significantly increased shoot length, root length, dry and fresh weight of shoot and root, number of fruits and flowers. Higher spores were counted in lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan inoculated plant compared to lessThan i greaterThan Gigaspora margarita, Sclerocystis dussii lessThan /i greaterThan and lessThan i greaterThan Acaulospora laevis lessThan /i greaterThan plants. The relationship between mycorrhiza and plant is very widely spread among terrestrial vascular plants. Inoculation with arbuscular mycorrhizal fungi (AMF) were significantly enhanced tomato shoots and root biomass. The endogenous species, lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan was the best species among four species tested. Pushpa.
