초록

Nutritious and functional foods from crop have received great attention in recent years. Colored-grain wheat contains high phenolic compound and a large number of flavonoid. One of plant pigments, wheat anthocyanin is increasingly emerging as natural compounds for consumer´s health and condition. Red grains and white grains with different antioxidant activity was used to conduct germination assay. Antioxidant enzyme assay of POD, APX, CAT, GST, GR and GPx was conducted during the imbibitional phase of mature seeds. Malondialdehyde (MDA) content was analyzed to assess the activity of ROS during imbibition phase of mature seeds and alpha-amylase contents were quantified for 3 days during dark imbibition. Additionally, sprouting rates of developing seeds in spikelet after anthesis with damp condition were measured in each red grain groups for two weeks to evaluate sprout ability affected by phytochemical of red grain wheat. In summary, we identified that red grain wheat showed higher antioxidant enzyme activity involved in ROS scavenging during imbibition. Sprouting rate during dark imbibition in developmental spikelet of four groups classified by color suggest that phytochemicals in dark red grain wheat caused negative effects to sprouting.
