Results for Standardized major axis (SMA) slopes and intercepts fitted within soil textures, corresponding to Figures 6, 7, and 8. Testing for common slopes (where slopes are equal, P>0.05) and intercept differences (where no differences in intercept, P>0.05). Type is defined in Figure 3. Plant size: M; Diameter of basal stem: D; Plant height: H; Likelihood ratio statistic: LR; Wald statistic: W.
