Fig. 1.

Responses to salt stress of total biomass (a), shoot biomass (b) and root biomass (c) in mycorrhizal halophytes and mycorrhizal glycophytes. Error bars represent 95% confidence intervals (CIs). Back-transformed effect sizes are shown above the bars. The numbers of studies are shown under the bars. Inoculation effects were considered significant when the 95% CIs did not overlap with zero. The P values for each panel reflect the significant differences between halophytes and glycophytes
