Principal Component Analysis (PCA) biplot showing the relationships among various physiological and biochemical traits in common beans under deficit watering (DW) and full watering (FW), with or without hormone application (ASAFA for acetylsalicylic acid foliar application and NFA for no foliar application), and bacteria inoculation (BI) versus non-bacteria inoculation (NBI). Positive correlations are indicated by vectors pointing in the same direction, while negative correlations are indicated by vectors pointing in opposite directions. Key parameters include hydrogen peroxide (H2O2), malondialdehyde (MDA), relative water content (RWC), proline (Pro), various chlorophyll contents (Chl.a, Chl.b, T.Chl), carotenoids (Cart), antioxidant enzymes (APX, GPX, CAT, SOD) and grain yield (GY).
