【摘要】 【目的】研究不同藠头种质资源的抗氧化能力，从不同地区挑选相应的藠头样品进行测定，采用试剂盒的方式最终筛选出优质的藠头种质。【方法】采集藠头样品，分别取其鳞茎，编号装入塑封袋中，放入-80℃低温保存。每次称取0.1 g样本测定APX、SOD、CAT、POD活性并比较它们之间的差异。【结果】在所测的样品当中，藠头的抗氧化酶活性差异显著。分析不同地区的样品资源发现湖北武汉和抚州SOD酶活性最高，其次是抚州和常德的POD酶活性较高，最后是抚州和云南的CAT酶活性较高。【结论】根据所测样品种质资源的抗氧化酶，可以看出SOD差异是最小的，APX差异较大。更多还原

【Abstract】 【Objective】To study the antioxidant capacity of different Chinese onion germplasm resources, and select corresponding samples from different regions for measurement, and select high-quality Chinese onion germplasm by means of kit. 【Methods】Collect the sample of A. chinense, take the bulb of A. chinense, number it, put it into plastic bag, and store it at-80 ℃. The activities of APX, SOD, CAT and POD were measured by weighing 0.1 g samples each time and the differences among them were compared. 【Results】 There were significant differences in antioxidant enzyme activities of A. chinense. It was found that the SOD activity in Wuhan and Fuzhou was the highest, followed by POD activity in Fuzhou and Changde, and CAT activity in Fuzhou and Yunnan was the highest. 【Conclusion】 According to the antioxidant enzymes of the germplasm resources, SOD showed the smallest difference, while APX showed the greatest difference.更多还原
