Drought is a serious environmental challenge that reduces the productivity of valuable crops, including wheat. Brassinosteroids (BRs) group phytohormones have been used to enhance wheat drought tolerance. Wheat cultivars with different adaptation strategies could their own specific tolerance mechanisms, and react differently treatment growth regulators. In this work, effect seed pretreatment 0.4 µM 24-epibrassinolide (EBR) was investigated in two (Triticum aestivum L.) contrasting behavior, tolerant Ekada 70 (cv. E70) sensitive Zauralskaya Zhemchuzhina ZZh), early ontogenesis under dehydration (PEG-6000) or soil conditions. EBR mitigated stress-induced inhibition seedling emergence growth, as well membrane damage cv.E70 but not ZZh. An enzyme-linked immunosorbent assay (ELISA) revealed substantial changes hormonal balance associated ABA accumulation drop levels IAA cytokinins (CKs) drought-subjected seedlings both cultivars, especially EBR-pretreatment reduced drought-induced hormone imbalance cv. E70, while it did same on EBR-induced content germ agglutinin (WGA) belonging protective proteins E70 suggest its contribution EBR-dependent adaptive responses. The absence detectable ZZh cultivar may be insensitivity pre-sowing treatment.
