(A) Heatmap hierarchical clustering of detected metabolites. Hierarchical trees were drawn based on detected metabolites in leaves of 0119 and 0226 at 0, 2, 8, 24, 48 and 72 h in control (CK) and salt stress treatment (S). The columns correspond to cultivar at different time points, while the rows represent different metabolites; (B) PCA loading plot of the two first principal components based on the metabolic data from leaves of 0119 and 0226 at 0, 2, 8, 24, 48 and 72 h in control (CK) and salt stress treatment (S).
