Mycorrhizal status of Argania spinosa (L.) Skeels in northeastern of Morocco

The argan tree, an endemic species in Morocco, has been exhaustively studied its southwestern range but neglected northeastern territory. Thus, the present study sets as objectives identification of arbuscular mycorrhizal fungi and evaluation tree’s roots’ mycorrhization level two stations: one region Béni Snassène (Berkane): Jebel Takermine with 7 prospected sites other at Aklim Alkabir 2 sites. At first station (Jebel Takermine), frequency Argania spinosa roots varied between 64% 100% root intensity 30.77% 66%. contents are higher (50.46%), 4 (50.33%), (39.44%) 1 (30.5%) against 18% 20% 6, 5 3. Argan trees from Jbel Alkbir, exhibited a high ranging 88% to 39.4% 73.4% respectively. Regarding vesicular rates, highest values were associated site 59.3% 29.4% respectively compared lowest rates 14% those 2. Spore densities rhizosphere stations 78 697 spores/100 g soil. isolated spores revealed presence 28 encompassing genera: Acaulospora, Dentiscutata Claroideoglomus, Funneliformis, Glomus, Rhizophagus, Pacispora, Families: Glomeraceae (7 species), Acaulosporaceae (10 Pacisporaceae (2 Claroideoglomeraceae Gigasporaceae (1 species).
