The influence of arbuscular mycorrhizal fungi (AMF) and rock phosphate (RP) was studied on Acacia gummifera, an endemic and Moroccan spontaneous species that is experiencing a regression. They are also a source of firewood, charcoal and precious air fodder in the dry season. The response of Acacia gummifera to a mixture of two species of arbuscular mycorrhizal fungi (Glomus intrardices and Glomus mossae) and two levels of rock phosphate (9 and 37 % of P equivalent of 0,25 and 0,5g P/kg of soil) was evaluated under greenhouse conditions. The arbuscular mycorrhizal root colonization varied from 10 % to 25 % when rock phosphate applications increased. Acacia seedlings grew poorly without arbuscular mycorrhizal fungi and without rock phosphate applications. However, AMF plants with RP applications achieved better results in terms of P and N concentration in shoot and root. In contrast, there were not additive effects of inoculation and phosphate application on total biomass. However, inoculation of acacias took up more P and N at 0.25 g P kg-1 of soil and above. These results suggest that AMF are able to absorb P from soil and rock phosphate for a better mineral nutrition of Acacia gummifera.
Author Keywords: Rock phosphate, arbuscular mycorrhizal fungi and Acacia gummifera.

Abstract
The influence of arbuscular mycorrhizal fungi (AMF) and rock phosphate (RP) was studied on Acacia gummifera, an endemic and Moroccan spontaneous species that is experiencing a regression. They are also a source of firewood, charcoal and precious air fodder in the dry season. The response of Acacia gummifera to a mixture of two species of arbuscular mycorrhizal fungi (Glomus intrardices and Glomus mossae) and two levels of rock phosphate (9 and 37 % of P equivalent of 0,25 and 0,5g P/kg of soil) was evaluated under greenhouse conditions. The arbuscular mycorrhizal root colonization varied from 10 % to 25 % when rock phosphate applications increased. Acacia seedlings grew poorly without arbuscular mycorrhizal fungi and without rock phosphate applications. However, AMF plants with RP applications achieved better results in terms of P and N concentration in shoot and root. In contrast, there were not additive effects of inoculation and phosphate application on total biomass. However, inoculation of acacias took up more P and N at 0.25 g P kg-1 of soil and above. These results suggest that AMF are able to absorb P from soil and rock phosphate for a better mineral nutrition of Acacia gummifera.
