The Effect of Short-Term Temperature Pretreatments on Sugars, Organic Acids, and Amino Acids Metabolism in Valencia Orange Fruit

Figure 5

Multivariate analysis of metabolites in Valencia orange fruits with different temperature treatments. (a): PLS-DA score plot. The blue circle represents the control group (CK); the orange triangle represents high-temperature treatment; the gray cross represents low-temperature treatment. (b): Correlation analysis between metabolites. The color depth and the dot size indicate the correlation strength; red indicates a negative correlation, and blue indicates a positive correlation. indicates , indicates , and indicates .
