Morphological characteristics of Shiluan02-1 and Hengzi151 seeds and profiles of metabolomics. a The seeds of Shiluan02-1 (left) and Hengzi151 (right), the scale bar is 0.5 cm. b PCA of metabolome data. The X-axis represents principal component 1 (PC1), the Y-axis represents principal component 2 (PC2), different samples are distinguished by different colors. c Hierarchical cluster analysis (HCA) based on the relative content of flavonoid compounds detected in the flavonoid pathway
