Abstract
This study aimed to investigate the biochemical changes caused by water stress and the effects of exogenous (24-epibrassinolide) EBL application on wheat crop. Two wheat genotypes, one stress-tolerant (HD-2733) and one stress-sensitive (DBW-187), were selected for the experiment. The experiment included four treatments: well-watered, water deficit, EBL-treated seed sown underwell-watered condition, and EBL-treated seed sown underwater deficit. EBL treatment improved the plants’ ability to withstand water stress, as indicated by improved biochemical parameters. This research emphasizes the significance of brassinosteroids (BR), particularly EBL, in enhancing wheat plants’ resilience to water deficit stress via improving biochemical parameters such as carbohydrate, protein, proline, photosynthetic pigments and phenol, resulting in yield improvement. EBL can be a potent compound to improve biochemical characteristics as well as yield per plant. Seeds of tolerant genotype treated with 0.01 m M EBL even under low moisture stress can be recommended.
