Table 3.
ANOVA table of shoot, crown root, and brace root architectural and anatomical measurements giving the F-value and significance for all factors and factor interactions
Architectural and anatomical phene abbreviations are as in Table 2, except amended with a crown root (CR) or a brace root (BR) prefix and including stem (St) width at that node. N level, density, and era are abbreviated N, D, and E, respectively, in the interaction terms.
