Abstract

The study included the role of key metabolites involved in oxidative defense, and osmotic adjustment under water stress is still undiscovered. We have evaluated whether antioxidant potential could be nominated as a potential marker of drought resistance in three maize hybrids (SC01, SC703, and SC720). Underwater deficiency in all maize hybrids decreased significantly compared to control samples in grain yield, photosynthetic pigments, and phenolic compounds. In contrast, proline and glycine betaine (GB) significantly increased. In contrast, a significant increase (p

干旱胁迫下玉米氧化防御系统和生理特性的变异

该研究包括参与氧化防御的关键代谢物的作用，而水分胁迫下的渗透调节作用仍未发现。我们评估了三个玉米杂交种（SC01、SC703 和 SC720）的抗氧化潜力是否可被提名为抗旱性的潜在标记。与对照样本相比，所有玉米杂交种在水下缺素情况下的谷物产量、光合色素和酚类化合物都显著下降。相反，脯氨酸和甘氨酸甜菜碱（GB）则明显增加。相比之下，丙二醛（MDA）这一脂质过氧化指标明显增加（p
