Dynamic changes of total phenolics in the core of 'Huahong' Apple. (a) Dynamic changes of total phenols in Huahong apples with different dwarfing interstocks at seven stages. (b) Total phenol content in Huahong apples with different dwarfing interstocks on June 9^th. (c) Total phenol content in Huahong apples with different dwarfing interstocks on October 8^th.

Figure 2. 

Dynamic changes in polyphenol components of different dwarfing interstocks represented as a river plot. (a) River plot of percentage composition of polyphenols. (b) River plot of polyphenol component contents. The horizontal axis represents time, spanning seven-time points from 9-Jun to 8-Oct; the vertical axis represents compound concentrations, ranging from 0 to 6,000. 1 was 'CG24', 2 was 'SH38', 3 was 'SH3', 4 was 'MD001', 5 was 'Mac9', 6 was 'CX5', and 7 was CK; A was 9-Jun, B was 29-Jun, C was 20-Jul, D was 8-Aug, E was 29-Aug, F was 18-Sep, and G was 8-Oct, respectively.

Trend analysis of dynamic changes in polyphenol components of 'Huahong' cores. The x-axis represents time, and the y-axis represents changes in expression.

Figure 5. 

PCA of polyphenol components in 'Huahong' core with different dwarfing interstocks. This PCA plot illustrates the distribution of various polyphenol compounds in the core of 'Huahong' fruit, influenced by different dwarfing interstocks. The first principal component (PC1) accounts for 95.4% of the variance, while the second (PC2) accounts for 2.4%, indicating that most of the variability in polyphenol composition can be explained by PC1. Different compounds are represented by distinct colors and shapes, showing how they cluster based on their PCA scores.
