Quinoa may be a promising alternative solution for arid regions, and it is necessary to test yield and mineral accumulation in grains under different soil types. Field experiments with (cv. CICA-17) were performed in Egypt in non-saline (electrical conductivity, 1.9 dS m) and saline (20 dS m) soils. Thirty-four chemical elements were studied in these crops. Results show different yields and mineral accumulations in the grains. Potassium (K), P, Mg, Ca, Na, Mn, and Fe are the main elements occurring in the quinoa grains, but their concentrations change between both soil types. Besides, soil salinity induced changes in the mineral pattern distribution among the different grain organs. Sodium was detected in the pericarp but not in other tissues. Pericarp structure may be a shield to prevent sodium entry to the underlying tissues but not for chloride, increasing its content in saline conditions. Under saline conditions, yield decreased to near 47%, and grain sizes greater than 1.68 mm were unfavored. Quinoa may serve as a complementary crop in the marginal lands of Egypt. It has an excellent nutrition perspective due to its mineral content and has a high potential to adapt to semi-arid and arid environments.
藜麦可能是干旱地区一种很有前景的替代解决方案，有必要测试不同土壤类型下藜麦的产量及籽粒中的矿物质积累情况。在埃及的非盐碱土（电导率为1.9 dS/m）和盐碱土（20 dS/m）中，对藜麦品种CICA - 17进行了田间试验。对这些作物中的34种化学元素进行了研究。结果表明，籽粒的产量和矿物质积累情况存在差异。钾（K）、磷（P）、镁（Mg）、钙（Ca）、钠（Na）、锰（Mn）和铁（Fe）是藜麦籽粒中的主要元素，但它们在两种土壤类型中的浓度有所变化。此外，土壤盐分导致了不同籽粒器官间矿物质模式分布的变化。在果皮中检测到了钠，但在其他组织中未检测到。果皮结构可能是防止钠进入下层组织的屏障，但对氯无效，这使得在盐碱条件下氯的含量增加。在盐碱条件下，产量下降至近47%，且不利于大于1.68毫米的籽粒大小形成。藜麦可作为埃及边缘土地上的一种补充作物。由于其矿物质含量，它具有良好的营养前景，并且具有适应半干旱和干旱环境的高潜力。
