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.

An ethno botanical survey was carried out with local population of Aguelmouss at khenifra province, in order to repertory therapeutic indications of spontaneous medicinal plants. So, an ethno botanical catalog was established in which medicinal plants widely used in this Moroccan area were reported with most of their pharmacological and medicinal virtues.

The present study is the purpose of valorizing medicinal plants and ethnopharmacological heritage of the Zerhoun region in Morocco, an ethnobotanical study has been carried with population. So, during spring 2014, a total of 350 interviews were going out in 19 towns. This study enabled to inventory 111 exploited species belonging to 43 families. Most of plants used are spontaneous and Lamiaceae dominates with 15 species (13.51%). Ethnobotany study revealed the leaves constitute the most used part (38%) and the most frequently employed mode of preparation for the majority of the remedies is the decoction (48%). Also, herbal remedies are often used to treat digestive disorders (37%).

With the purpose of valorizing the Asteraceae family and ethnopharmacological heritage of the Meknes Tafilalet area in Morocco, an ethnobotanical study has been carried. A total of 344 interviews were done with out into the herbalists, traditional healers and druggists in the region of this area. This study enabled to inventory 48 exploited species belonging to 31 genera used to treat a variety of human diseases ; so, herbal remedies are often used to treat digestive disorders (18.6%), followed by the treatment of cardiovascular disorders (13.1%) and metabolic ones (12.5%). The leaves constitute the most used part (31.8%) and the most frequently employed modes of preparation for the majority of the remedies are the decoction (63.4%). Also, the species frequently used are : Anacyclus pyrethrum (11.6%), Dittrichia viscosa (7.6%) and Atractylis gummifera, Echinops spinosus and Calendula officinalis with 5.2 % each one.
