Identification of potential phenolic biomarkers via partial least squares-discriminant analysis (PLS-DA). Score scatter plot of the two-component PLS-DA model based on the concentration of detected phenolic compounds during the 2012 (a) and 2013 (b) seasons showing the discrimination between the control and cluster bagging-treated groups. Loading scatter plot of PLS-DA showing the important phenolic compounds (|Pcorr| value ≥0.8 and VIP value ≥1) during the 2012 (c) and 2013 (d) seasons that contributed significantly to the distinction between the control and cluster bagging-treated groups.
