“Both AMF inoculation and AMF + DSE co-inoculation, but not DSE inoculation, significantly increased the chlorophyll contents in maize leaves, resulting in stronger photosynthetic physiology, higher biomass, and increased length, surface area, volume, branches, tips number, and mass density (RTD) of maize roots, but decreased specific root length (SRL), specific root area (SRA), specific root branches (SRB), and specific root tips (SRT).”
