Fig 4. Between-element correlations of concentrations in tissues of barley ILs.

Fig 4

Pearson correlation coefficients (r) are given for (A) the young leaf, (B) the flag leaf and (C) grains. Values are based on least-square means of 54 ILs and the recurrent parent Scarlett. Correlations exhibiting r > |0.27|, |0.35| and |0.44| are statistically significant at P < 0.05 (light grey), 0.01 (dark grey) and 0.001 (black), respectively, according to a two-tailed distribution and n = 55 observations. Measurements were from the same experiment as shown in Fig 1.
