Fig. 3.
The pairwise correlations of all of the root variables for which the correlation with at least one other variable is of magnitude at least 0.5. The lower-left panels show the numerical values of the correlations (rounded to two decimal places). The upper-right panels show the scatter plots. All variables are scaled to have a mean of zero and a variance of 1. Abbreviations: G1, Geom1; TL, total length; ALSR, average length – seminal roots; ALLR, average length – lateral roots; LRC, lateral root count; CH, convex hull; MW, maximum width; MD, maximum depth; WDR, width–depth ratio.
