Fig. 2From: Do halophytes and glycophytes differ in their interactions with arbuscular mycorrhizal fungi under salt stress? A meta-analysisResponses to salt stress of proline (a), soluble sugar (b) and soluble protein (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 glycophytesBack to article page
