Principal Component Analyses (PCA) built using morphological traits (circles): stem biomass (SB), root biomass (RB), height (Hgh), total leaf area (TLA), leaf number (LN) and specific leaf area (SLA). Epigenetic variables (triangles): percentages of methylation of cytosine residues (%mC), histone H3 and H4 acetylation ratios (respectively AcH3 and AcH4) have been projected as supplementary variables using their Pearson coefficients with scores of PCA as coordinates. (A) in well-watered condition, (B) in water deficit condition.
