  The ability of endomycorrhizal fungi to colonize tomato (Lycopersicum esculentum. Mill) roots, was studied under glasshouse conditions. Two indigenous species; Glomus mosseae and Scutellospora sp. and non-indigenous species Gigaspora margarita were used in the study. Pot culture technique was used for re-culturing G. mosseae and Scutellospora sp., sorghum was used as a trap host. Gigaspora margarita was re-cultured by test tube technique. All species had the ability to colonize tomato root with different colonization levels. Significantly higher root were colonized by G. mosseae (80%) compared to G. margarita (20%). A G. mosseae significantly increased shoot dry weight (2.82 g) and flowers number (32.75 g) and root growth. Tomato plants treated by G. mosseae were higher significantly after seven week of plant growth. The colonization of tomato root by G. mosseae lead to bigger root size and more branching which increase positively the number of root tips, length, surface area and root volume. Higher spores (455/100 g) were counted in Glomus mosseae inoculated plant compared to Scutellospora sp. (250/100 g) and G. margarita plant (132/100 g).

  The study aimed to select plant host for multiplication of Glomus mosseae spores. Five plant species were used [(corn, (Zea mays) sorghum, (Sorghum bicolor) lentil, (Lens culinaris), barley, (Hordeum vulgare) and green bean, (Phaseolus vulgaris)]. Plants were inoculated with Glomus mosseae and grown for 75 days under glasshouse conditions. Mycorrhizal sporulation and colonization of all plant hosts were assessed at different sampling periods. At 75 days of growth the highest number of Glomus mosseae spores was found in mycorrhizosphere of corn plant (167 spore/10 g soil), while the lowest in the mycorrhizosphere of barley (35 spore/10 g soil). The highest percentage of root colonization was in corn (76%), while the lowest colonization was found in green bean (24%). Corn was the most suitable host for spore production of Glomus mosseae and to extensive root colonization. It was recorded that plants having more colonization percentage were able to produce more Glomus mosseae spores. The study indicated that different plant species significantly influenced the root spore production and root colonization percentage of Glomus mosseae.
