t1“Sunflower (Helianthus annuus L.), a globally significant oilseed crop, faces substantial yield losses due to drought stress, a major environmental constraint. In this study, the effects of nitric oxide (NO) to increase drought tolerance in four sunflower genotypes (resistant Irtysh, RAR 56 and sensitive Zarya, RAR 133) showing different stress responses were investigated. Conducted in a controlled hydroponic system, …” Show full quote
