Figure 5.

Correlation network for the contents of the nine compounds and the total contents detected in red clover. The significant correlations (|r| > 0.50 and p < 0.05) are indicated with red lines. The positive correlations are indicated with solid line. The negative correlations are indicated with dotted lines. The weak correlations (|r| < 0.50) are indicated with grey lines. Thicker lines indicate a stronger correlation. The length of each line has no meaning.
