Nanoscale zero-valent iron (FeNPs) can affect plant growth and water uptake positively or negatively. Yet, its mechanism is still unclear, particularly for differentiate functional roles of FeNPs in plant-soil interaction. To address this issue, we first confirmed 1.0 and 1.5 g·kg-1 FeNPs as growth-promotion concentrations and 1.5 g·kg-1 as optimal one, while 2.0 g·kg-1 turned to restrict growth in maize seedlings, comparing with CK. When AM fungus (Funneliformis mosseae) was inoculated and cultured with FeNPs, 1.0 and 1.5 g·kg-1 FeNPs further evidently enhanced water uptake and biomass accumulation (P |
