Pearson’s correlations of yield values, standardized to account for differing moisture levels, with seminal (A,C) and nodal (B,D) root numbers (A,B) and angles (C,D) of wheat plants field-grown in two growing regions in Central and Southern Sweden. Regression lines are fitted based on the precrop of either OSR (yellow) or wheat (blue), with a facet grid dividing the root data by collection during the elongation phase (2021) and flowering phase (2020 & 2021).
