Fig. 2

a The principal component analysis (PCA) model among “Hutou” jasmine flower samples by HS-SPME-GC/MS at five flowering stages. b Hierarchical cluster analysis (HCA) of the identified metabolites in different flower samples. Each sample is represented by a column, and metabolite information is represented by a row. The relative contents are indicated by the different shade colors in the Z-score (i.e., red and green), with red representing high contents and green indicating low contents. c Variation trend of total volatiles content. Data are represented as means±standard deviations (SD) d Classes and proportions of a total of 912 metabolites detected in “Hutou” jasmine flowers. e Venn diagram shows the numbers of the overlapping and unique significant differential metabolites (SDVs) among the four comparisons. f, g KEGG enrichment analysis of SDVs in F1 vs. F2 and F1 vs. F3 comparison groups. The size and color of the bubbles represent the count of metabolites involved in a certain pathway and the P-value of the rich factor, respectively. The red fonts indicate metabolic pathways associated with fragrance synthesis (P < 0.05).
