Protective effect of 24-epibrassinolide on wheat plants under water deficit

Abstract

We studied the effect of 24-epibrassinolide (EB) on growth, proline content, the state of wheat seedling antioxidant system under water deficit, modeled by 12% polyethylene glycol (PEG). It was found that under drought EB-pretreatment has a protective effect on wheat plants, stabilizing the state of the antioxidant system, regulating the balance of hydrogen peroxide and peroxidase activity, as well as inducing the additional accumulation of proline, which was reflected in maintaining a higher level of mitotic activity in apical root cells of these plants.
