Phenolic compounds, antioxidant enzymes, and oxidative stress in barley (Hordeum vulgare L.) genotypes under field drought-stress conditions.

ABSTRACT: Climate change has exacerbated drought, making water scarcity a significant constraint on crop production. This study aimed to evaluate drought stress responses of 21 barley cultivars and breeding lines, using various traits of leaf oxidative stress [DPPH radical scavenging, malondialdehyde (MDA), and hydrogen peroxide (H₂O₂)], antioxidants (enzymes and polyphenols), photosynthetic pigments and chlorophyll fluorescence (F) [carotenoid (Car), chlorophyll (Chl), F_m, F₀, and F_v/F_m], relative water content (RWC), electrolyte leakage (EL), proline (Pro), protein content (PC), and grain yield. Field experiments were conducted under both normal and drought stress conditions. Significant effects of moisture conditions were observed
