Synergistic Seedling Responses of Distinct Oat Cultivars to Compound Saline–Alkali Stress: Phenotypic, Physiological, and Metabolomic Mechanisms
Simple Summary Soil salinization and alkalinization severely restrict crop growth and agricultural production in cold highland areas. Most previous studies on oats have only focused on single-salt stress, whereas systematic and multi-dimensional investigations of oat responses to compound salt–alkali stress remain limi...
