Effects of Rhizophagus intraradices on net photosynthetic rate (Pn), stomatal conductance (gs), intercellular CO2 concentration (Ci), and transpiration rate (E) in Sophora davidii leaves at different levels of As stress. Note: the same letter in each column indicates no significant difference among treatments at P < 0.05 using Tukey’s test; values are means ± SD, n = 3; *P < 0.05, **P < 0.01, NS not significant
