A Comparative Analysis of the Effect of 24-Epibrassinolide on the Tolerance of Wheat Cultivars with Different Drought Adaptation Strategies Under Water Deficit Conditions.

Drought is a serious environmental challenge that reduces the productivity of valuable crops, including wheat. Brassinosteroids (BRs) is a group of phytohormones that have been used to enhance wheat drought tolerance. Wheat cultivars with different adaptation strategies could have their own specific drought tolerance mechanisms, and could react differently to treatment with growth regulators.

Nitric Oxide (NO) Improves Wheat Growth under Dehydration Conditions by Regulating Phytohormone Levels and Induction of the Expression of the Dehydrin Gene.

Nitric oxide (NO) is a universal signaling molecule with important regulatory functions in the plant's life cycle and adaptation to a wide spectrum of environmental stresses including drought. The effect of pre-sowing seed treatment with the donor of NO sodium nitroprusside (SNP, 200 μM) on wheat L. plants subjected to dehydration (PEG-8000, 12%) was investigated.
