In the face of escalating environmental challenges, understanding crop responses to abiotic stress is pivotal for sustainable agriculture. The present study meticulously investigates intricate interplay between drought and salinity in barley ( Hordeum vulgare L.). Employing three distinct genotypes—Traveller, Prunella, Zahna—we scrutinize their physiological, biochemical, molecular adaptations under conditions. Our findings underscore genotype-specific responses, unravelling multifaceted...
