Principal component analysis of sunflower leaf metabolomic data obtained using targeted measurements of major compounds and untargeted LC-MS-Orbitrap analyses of ethanolic extracts. Leaves were harvested on parental lines (closed symbols) and their hybrids (open symbols) cultivated in Heliaphen phenotyping facility in well-watered or water-deficit conditions. A. Scores plot on the PC1 × PC2 plan for targeted measurements (6 variables). B. Scores plot on the PC1 × PC2 plan for LC-MS profiles (4843 variables). Green, well-watered; Orange, water-deficit.
