Previous studies have shown that salinity eustress enhances the nutritional and bioactive compounds and antiradical capacity (ARC) of vegetables and increases the food values for nourishing human diets. Amaranth is a salinity-resistant, rapidly grown C4 leafy vegetable with diverse variability and usage. It has a high possibility to enhance nutritional and bioactive compounds and ARC by the application of salinity eustress. Hence, the present study aimed to evaluate the effects of sodium chloride stress response in a selected Lalshak (A. gangeticus) genotype on minerals, ascorbic acid (AsA), Folin−Ciocalteu reducing capacity, beta-carotene (BC), total flavonoids (TF), pigments, polyphenolic profiles, and ARC. A high-yield, high-ARC genotype (LS6) was grown under conditions of 0, 25, 50, and 100 mM sodium chloride in four replicates following a block design with complete randomization. We recognized nine copious polyphenolic compounds in this accession for the first time. Minerals, Folin−Ciocalteu reducing capacity, AsA, BC, pigments, polyphenolic profiles, and ARC of Lalshak were augmented progressively in the order: 0 < 25 < 50 < 100 mM sodium chloride. At 50 mM and 100 mM salt concentrations, minerals, AsA, Folin−Ciocalteu reducing capacity, BC, TF, pigments, polyphenolic profiles, and ARC of Lalshak were much greater than those of the control. Lalshak could be used as valuable food for human diets as a potent antioxidant. Sodium chloride-enriched Lalshak provided outstanding quality to the final product in terms of minerals, AsA, Folin−Ciocalteu reducing capacity, BC, TF, pigments, polyphenolic profiles, and ARC. We can cultivate it as a promising alternative crop in salinity-prone areas of the world.
先前的研究表明，盐分适度胁迫可提高蔬菜的营养和生物活性化合物含量以及抗自由基能力（ARC），并增加用于滋养人类饮食的食物价值。苋菜是一种耐盐、生长迅速的C4叶菜类蔬菜，具有多种变异性和用途。通过施加盐分适度胁迫，它极有可能提高营养和生物活性化合物含量以及ARC。因此，本研究旨在评估选定的拉尔萨克（A. gangeticus）基因型对矿物质、抗坏血酸（AsA）、福林-西奥尔特试剂还原能力、β-胡萝卜素（BC）、总黄酮（TF）、色素、多酚谱以及ARC的氯化钠胁迫响应效应。采用完全随机区组设计，将一个高产、高ARC基因型（LS6）在0、25、50和100 mM氯化钠条件下种植，重复四次。我们首次在该种质中鉴定出九种丰富的多酚化合物。拉尔萨克的矿物质、福林-西奥尔特试剂还原能力、AsA、BC、色素、多酚谱以及ARC随氯化钠浓度的增加依次递增：0 < 25 < 50 < 100 mM氯化钠。在50 mM和100 mM盐浓度下，拉尔萨克的矿物质、AsA、福林-西奥尔特试剂还原能力、BC, TF、色素、多酚谱以及ARC均远高于对照。拉尔萨克作为一种强效抗氧化剂，可作为人类饮食的优质食物。富含氯化钠的拉尔萨克在矿物质、AsA、福林-西奥尔特试剂还原能力、BC、TF、色素、多酚谱以及ARC方面为最终产品提供了卓越品质。我们可以将其作为世界盐碱化地区一种有前景的替代作物进行种植。
