Table 1.
Native (China) and invasive (US) populations of tallow that were used in this study.
Figure 1.
Soil salinity and conductivity in different saline stress treatments.
Values are means + 1 SE. Means with the same letters were not significantly different in post-hoc multiple comparisons of means at the P = 0.05 level.
Figure 2.
Functional traits of invasive and native population of tallow in different saline stress treatments.
(a) Final height, (b) height growth rate, (c) stem mass, (d) aboveground mass (e) root mass, and (f) root to shoot ratio. Values are means ± 1 SE. P-values are the significance of the interaction effect between origin×saline (full ANOVA results are in Table 2). Asterisk (*) indicates significant differences between invasive and native populations in a saline stress treatment at the 0.05 level according to post-hoc multiple comparisons of means in ANOVA.
Figure 3.
Leaf functional traits of invasive and native population of tallow at different saline stress treatments.
(a) Leaf area, (b) leaf mass, (c) SLA and (d) LAR. Values are means ± 1 SE. P-values are the significance of the interaction effect between origin×saline (full ANOVA results are in Table 2). Asterisk (*) indicates significant differences between invasive and native populations in a saline stress treatment at the 0.05 level according to post-hoc multiple comparisons of means in ANOVA.
