The effectiveness of vesicular arbuscular mycorrhizas (AM) (Glomus mosseae, Glomus etinicatum, Glomus fasciculatum and Glomus Caledonium) on plant development of soilless grown muskmelon was investigated. Plants were cultivated in a plastic house, in perlite substrate. Investigated plant growth parameters were plant height, stem diameter, number of leaf, fresh weights of root, stem and leaves. Results showed that all mycorrhiza species increased the plant growth of melon plant in comparison to non inoculated control plants. However, among AM fungi species the better plant growth was obtained with Glomus coledonium and Glomus fasciculatum.
