The relative growth rates (RGRs) of the 4 species influenced by salinity stress and simulated herbivory.

<p>Legends (SH0%, SH25% and SH50%): 0, 25 and 50% of the leave area of the plant was removed by simulated herbivory. Salinity stress: watered with 0, 4 and 8 g L⁻¹ NaCl solution. Bonferroni corrections were used for the multiple comparison analyses, and significant differences (at the significance level of α = 0.05) are considered to be present between two treatments with different symbols. Error bars represented Mean ± SE (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048829#pone.0048829.s004" target="_blank">Table S3</a> for supplementary test statistics).
