摘要： This study evaluated 27 malt barley (Hordeum vulgare L.) varieties for key nutritional and functional components - total flavonoids, gamma-aminobutyric acid (GABA), alkaloids, and protein - in barley grass powder across contrasting winter and summer seasons. All two-row varieties, provided by the Yunnan Academy of Agricultural Sciences, were grown under a randomized complete block design in Kunming, China. Functional components were quantified using colorimetric and Kjeldahl methods, with data analyzed through ANOVA, Tukey's HSD, percent change calculations, biplots, and hierarchical clustering. Results showed highly significant genotypic, seasonal, and genotype x season interaction effects for all traits. Concentrations of all components were higher in winter, reflecting enhanced biosynthesis under cooler temperatures. Varieties V5, V13, V14, V16, and V21 consistently exhibited high and stable functional profiles across seasons, while V3, V7, V9, V18, and V26 were more sensitive to analyses revealed strong positive correlations among traits and clearly distinguished superior genotypes, highlighting their genetic stability. Lower coefficients of variation in winter suggested greater trait stability under cooler conditions. The study underscores the influence of genotype x environment interactions on the functional quality of barley grass powder and identifies resilient genotypes suitable for functional food development. These findings provide a valuable foundation for breeding climate-resilient, nutritionally superior barley cultivars and promote the use of barley grass in health-oriented applications.
