The effects of arbuscular mycorrhizal fungal (AMF) inoculum (M) individually and in combination with rhizobia (R) and Pseudomonas fluorescens (Pf) were investigated on the growth and nutrition of A. senegal seedlings. In glasshouse conditions, all the inocula except Pf significantly enhanced A. senegal plant growth after 6 months in a non-sterile soil from Dahra (Senegal). However, no significant increase in shoot N content was recorded, whereas the application of MR, MPf and MRPf significantly improved shoot P content, and that of MR and MPf, shoot K content. The nodule number was significantly augmented by rhizobial inoculation and the root mycorrhizal colonization rate by MR, MPf and MRPf treatments. Soil spore density was increased by all inoculants except MPf, and soil AMF hyphal length by M, R and MRPf treatments. The inoculation with Pseudomonas and MPf significantly stimulated soil acid phosphatase activity, but no significant effect was observed on soil fluorescein diacetate (FDA) activity. Thus, the dual inoculation with AMF and R can be beneficial to A. senegal growth under non-sterile soil, where nutrients particularly P and N are often deficient Exemplaires

Catégories : FORESTERIE Mots-clés : Acacia senegal, Arbuscular mycorrhizal fungi, Mycorrhizal root colonization, Relative mycorrhizal dependency, Soil fertility, Agroforestry Résumé : The benefits of inoculation with six arbuscular mycorrhizal fungi (AMF) isolates (Glomus aggregatum, G. fasciculatum, G. intraradices, G. manihotis, G. mosseae, and G. verriculosum) were investigated on seedlings of Acacia senegal (L.) Willd., a multipurpose tree legume highly valued for arabic gum production. Mycorrhizal root colonization, plant growth and relative mycorrhizal dependency (RMD) were measured in A. senegal seedlings growing in soils from three geo- graphical sites in Senegal (Dahra, Bambey and Goudiry) and two soil conditions (sterilized vs unsterilized) in the glasshouse. The impact of inoculation on mycorrhizal root colonization and plant growth depended on AMF isolates, soil origins and soil conditions. Mycorrhizal root colonization and plant growth were increased in sterilized soils regardless of soil origin and AMF isolates. The degree of RMD of A. senegal seedlings varied with soil origin, soil condition and AMF isolates. A. senegal showed the highest RMD values, reaching a maximum of 45 %, when inoculated with G. manihotis. However, in unsterilized soils, no significant effect of AMF inoculation on plant growth was observed despite significant root colonization with certain AMF isolates in Dahra and Goudiry soils. This indicates that the most infective AMF isolates were not the most effective and unsterilized soils may contain effective mycorrhizal propagules. In conclusion, it is important to consider the native mycorrhizal component of the soils before harnessing mycorrhizal inoculation programs for sustainable agroforestry systems. Exemplaires

Catégories : FORESTERIE Mots-clés : Arbuscular mycorrhizal fungi, rhizobia, Acacia senegal, enzyme activities, non-sterilized soil. Résumé : Acacia senegal (L.) Willd. is a multipurpose legume that is economically and ecologically important in Sahelian areas, especially in Senegal. It has long been used for arabic gum production. However, drought and overexploitation lead to decreased soil fertility and tree productivity. An experiment was conducted to examine the response of A. senegal seedlings to inoculation with mixed arbuscular mycorrhizal fungi (Glomus fasciculatum, Rhizophagus irregularis and Glomus verriculosum) and rhizobial strains (ORS 3574, ORS 3593, ORS 3607 and ORS 3628) in glasshouse conditions. After 6 months of culture under non-sterilized field soil from Dahra (northern part of Senegal), plant height, arbuscular mycorrhizal root colonization rate and soil acid phosphatase activity were significantly enhanced by the combined inoculation of arbuscular mycorrhizal fungi (AMF) and rhizobia. However, plant biomass, soil spore density and hyphal length were significantly improved by the single inoculation with mycorrhizal or rhizobial strains. The number of nodules was higher for rhizobial inoculated plants. No significant increase in shoot nutrient contents was observed after inoculation. The microbial inoculation enhances the soil acid phosphatase activity whereas no positive effect was noticed on soil total microbial activity. These results indicate that the single inoculation with AMF or rhizobia improves A. senegal seedling growth under this non-sterilized field soil better than the dual inoculation. It is suggested that, for the success of a dual inoculation, a careful selection of effective combinations of microsymbionts is necessary to enhance plant growth and soil bio-functioning and for restoration of soil fertility in a given environment.
