摘要

The aim of our work was to assess the effect of inoculation with three arbuscular mycorrhizal fungi (AMF) (Rhizoglomus aggregatum (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oeh., Funneliformis mosseae (T.H. Nicolson and Gerd.) C. Walker and A. Schüssler. and Rhizoglomus intraradices (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oehl.), and a mixed inoculum of these AMF on root colonization, biomass production, mycorrhizal dependency (MD) and shoot mineral contents of two salt tolerant grasses Leptochloa fusca L. Stapf and Sporobolus robusts Kunth. After four months of growth in a sterilized soil and greenhouse conditions, grasses inoculated with AMF showed significantly higher total biomass production than non-inoculated seedlings. MD and shoot mineral contents (especially P) varied with AMF host plants. Maximum values of MD (13%) were observed in L. fusca and S. robustus seedlings when inoculated with R. intraradices and F. mosseae, respectively. Only P contents were higher in the S. robustus/mixed-AMF combinations than the other treatments. These results demonstrate the potential benefits in our experimental conditions of AM inoculation for improving growth and P acquisition particularly in the L. fusca/ F. mosseae and S. robustus/mixed-AMF combinations.

Stapf和Sporobolusrobusts Kunth的含量。在无菌土壤和温室条件下生长四个月后，接种AMF的草显示出的总生物量明显高于未接种的幼苗。 MD和芽的矿物质含量（特别是P）随AMF宿主植物而变化。当分别用根瘤菌和苔藓菌接种时，在福寿螺和稳健链霉菌幼苗中观察到MD的最大值（13％）。稳健链球菌/混合AMF组合中仅P含量高于其他处理。这些结果表明，在我们的AM接种实验条件下，特别是在L. fusca / F. mosseae和S.robustus /混合AMF组合中，可以改善生长和磷的吸收。
