({G}melina, {Y}emane) is a fast growing tree, native from {I}ndia and considered as a potentially invasive woody plant in {W}est {A}frica. {M}ycorrhizal inoculation of seedlings with {G}lomus intraradices was performed to study (1) the effect on the growth of {G}. arborea, (2) the impact on the catabolic diversity of soil microbial communities and (3) the influence on the structure of herbaceous plant species communities in microcosms. {T}reatments consisted of control plants, pre-planting fertilizer application and arbuscular mycorrhizal ({AM}) inoculation. {A}fter 4 months' culture in autoclaved soil, {G}. arborea seedlings were either harvested for growth measurement or transferred into containers filled with the same soil but not sterilized. {O}ther containers were kept without {G}. arborea seedlings. {A}fter 12 months' further culture, effects of fertilizer amendment and {AM} inoculation on the growth of {G}. arborea seedlings were recorded. {AM} colonization was significantly and positively correlated with plant diversity. {T}he substrate-induced respiration response to carboxylic acids was significantly higher in the absence of {G}. arborea and in the presence of {G}. intraradices as compared to the other treatments. {T}he influence of {AM} symbiosis on plant coexistence and on allelopathic processes of invasive plants are discussed.}, keywords = {{AMF} ; plant diversity ; catabolic diversity ; {G}lomus intraradices ; {G}melina arborea}, booktitle = {}, journal = {{M}ycorrhiza}, volume = {16}, numero = {2}, pages = {125--132}, ISSN = {0940-6360}, year = {2006}, DOI = {10.1007/s00572-005-0024-7}, URL = {https://www.documentation.ird.fr/hor/fdi:010041609}, }
