PLS-PM analysis of polyphenols (A, B) and plastid pigment (C, D). Red and green arrows indicated positive and negative correlation, respectively. The thickness of arrow means the magnitude of the path coefficient in the model. Numbers and *, **, *** on the arrows show the path coefficient and the significant differences of 0.05, 0.01, 0.001, respectively. The model was assessed using the Goodness of Fit (GoF).
