Table 3. Genotype × treatment trait estimates.
Modeled traits show median of posterior distribution (95% credible interval range), while observed traits show mean values (sd). Boldface indicates significance relative to well-watered conditions at P < 0.05 or for 95% confidence interval (CI). HDI interval difference not intersecting with zero was used to describe a credible trait variance (Amax and s).
