Preliminary analysis of metabolomics data. (A) PCA score plot metabolite profiles from ‘Zibao’ Fig. (CK) and the after bagging female flower tissues (BF). (B) Volcano plots of SCMs between CK and BF. (C) Cluster analysis of metabolites from samples of CK and BF. The colour indicates the level of accumulation of each metabolite, from low (green) to high (red). The Z-score represents the deviation from the mean by standard deviation units. (D) KEGG classification of DEGs between CK and BF
