In a pot experiment conducted in a growth chamber. the influence of five species of arbuscular fungi (Glomales) on growth and mineral nutrition of winter wheat (Triricum aestivum) cv. Salwa was investigated. After nine weeks of growth, plants inoculated with Glomus calcdonium and G. mosseae were significantly higher than those from control pots and those with G. constrictum, G. deserticola and G. macrocarpum mycorrhizae. All fungi significantly increased root dry weights, although G. caledonium was the most effective species. Except for G. constrictum, the other fungi significantly increased shoot dry weights of plants, with G.caledonium being the most effective species. G. caledonium, G. macrocarpum and G. mosseae significantly decreased root: shoot ratios. Inoculations significantly affected shoot and root N, P, K, Ca and Mg concentrations. Except for G. constrictum, all the other fungi significantly increased shoot N and Ca contents. Shoot P and K contents were significantly higher in plants harbouring only G. caledonium mycorrhizae. G. caledonium. G. deserticola and G. mosseae significantly increased shoot Mg contents. Except for G.constritum, the other fungi significantly enhanced root N and P contens. The fungi significantly increasing root K supplies were G. caledoniumum, G. macrocarpum , and G. mosseae. Root Ca contents was significantly increased only in G. constrictum treatment. Except for G. constrictum and G. mosseae, the other fungi significantly increased root Mg contents, with G. macrocarpum ranking the first. Shoot and root dry weights and shoot N and K as well as root N and P contents in T. aestivum were significantly correlated with mycorrhizal colonization.
