Figure 2.
QQ scatterplots, histograms, coefficient of correlation, and box plots between K-use efficiency (KUE) traits from hydroponic experiment. Lower half of matrix and the center line cutting the figure into two triangles represent histograms for each trait. Box plots are presented at the extreme right of upper triangle. Between the histograms in lower triangle are QQ scatter plots. Between the box plots and histograms in the upper triangle are coefficient of correlation (r 2 values) in control and treatment; x and y axes of histograms and scatter plots represent phenotypic distribution of traits. *cf. Trait nomenclature is presented in Table 2 legends.
