摘 要 ：对我国沿海地区新收集种质资源金藜麦(Chenopodium quinoa Willd.)进行了耐盐性及营养品质评价。结果表明：金藜麦在对盐胁迫相对敏感的芽期和苗期表现出相对较高的耐盐性； 子粒蛋白质含量为14.2%，蛋白营养价值优于牛奶以及小麦、水稻、玉米、大豆等作物；子粒中富含维生素B、E等以及钙，锰，铁，铜，锌等矿质元素，特别是钙含量高达190.16 mg/100g，是小米钙含量的35倍；且金藜麦子粒含有丰富的必需脂肪酸，如亚油酸（3.58 g/100g）和亚麻酸（0.44 g/100g），天然抗氧化剂维生素E含量为7.66 mg/100g。这些研究结果表明，新收集的金藜麦种质资源，具有较高的营养价值和耐盐性，将为我国藜麦研究和种植利用提供重要的种质资源。

Abstract:Golden quinoa，collected from China coast area，was evaluated with its nutritional quality and its salt tolerance ability in this study. The results showed that the seeds of golen quinoa are considered as a nutritionally complete food with high protein content (14.2%) and an outstanding composition of essential amino acids. The protein quality of golden quinoa seeds was far superior to that of milk and some common crops. The seeds are rich in vitamins (B，E) and several minerals including Ca2+， Mn2+，Fe3+，Cu2+， and Zn2+，and the Ca2+ content of golden quinoa is 190.16 mg/100g，35 fold higher than that of millet. Moreover，they provide a valuable source of carbohydrates and essential fatty acids，the content of linoleic acid and linolenic acid were 3.58 g/100g and 0.44 g/100g. These results showed that the golden quinoa owes the excellent nutritional quality and naturally high tolerance to salt stress，which providing the excellent germplasm resources for quinoa study and planting.
