Abstract

Growth response of four tree species  Tectona grandis , Gmelina arborea, Corymbia citriodora and Khaya senegalensis, were examined to adding exotic vascular arbuscular mycorrhiza (VAM) and soil conditioner "REVITA.SAN" to sandy soil in Serabioum plantation at  Ismailia government, that irrigated with treated sewage water to enhance soil properties and moisture, from 2013 to the end of 2015. Results showed that treatments included soil conditioner such as soil conditioner (Sc) and soil conditioner and mycorrhiza (Sc+ M) recorded the highest values of all growth parameters for all studied species, especially with Corymbia citriodora, except for chlorophyll (a+b) that recorded the highest values with (M) treatment in Tectona grandis. Moreover, all examined roots of all studied species that have previously inoculated with VAM have been colonized with mycorrhizal structures e.g., internal hyphae and vesicules.
