Contrasting responses of alfalfa (Medicago sativa) accessions to combined water and nutrient stress: integrated morphological, biochemical, and molecular analyses.

Abstract excerpt

Combined water deficit and nutritional deficiencies pose significant challenges to the productivity of alfalfa (Medicago sativa). We evaluated natural variation in 14 Tunisian accessions under combined stress, and identifed two contrasting genotypes, Radhouane (tolerant) and Kettana 1 (sensitive), for detailed analysis. Multivariate analyses, including Principal Component Analysis and clustering, showed clear...
