Viking 3000 alfalfa seeds irradiated with gamma rays to doses of 0, 1, 2, 3, or 4 kGy were sprouted and allowed to grow for up to 8 days at 23 degrees C. Germination, growth (yield and length), antioxidant capacity, and ascorbic acid (AA) were measured during sprouting. Results showed percent germination of the seeds and the rates of growth of the sprouts were inversely related to the radiation dose absorbed by the seeds. Both antioxidant capacity and AA content expressed on a fresh weight basis decreased during growth of the sprouts. Sprouts grown from irradiated seeds had greater antioxidant capacity and AA content on a fresh weight basis than those grown from nonirradiated seeds. However, when the nutritive values were expressed on a per gram of seed basis, irradiation had no effect on the nutritive values of sprouts.
将紫花苜蓿种子“维京3000”用伽马射线辐照至0、1、2、3或4千戈瑞的剂量，然后进行发芽处理，并在23摄氏度下使其生长长达8天。在发芽过程中测量发芽率、生长情况（产量和长度）、抗氧化能力和抗坏血酸（AA）。结果表明，种子的发芽率和豆芽的生长速率与种子吸收的辐射剂量呈负相关。以鲜重计，在豆芽生长过程中，抗氧化能力和AA含量均下降。与未辐照种子长出的豆芽相比，辐照种子长出的豆芽以鲜重计具有更高的抗氧化能力和AA含量。然而，当以每克种子计表示营养价值时，辐照对豆芽的营养价值没有影响。
