In order to promote the storage and growth of potato seedlings, the antioxidant activities of potato seedlings at different storage temperatures were analyzed. The antioxidant activities of potato seedlings at two different temperatures were compared. In addition, the effects of high temperature and normal temperature on the growth phenotype and antioxidant system physiological indexes of potato seedlings were analyzed by high temperature treatment. According to the significant change characteristics of SOD activity of antioxidant index at different temperatures, the SOD genes of potato were screened and bioinformatics analysis and gene expression analysis were carried out. The results showed that high temperature inhibited the antioxidant activity of potato seedlings and affected the growth of potato seedlings. The growth of potato seedlings can be promoted in medium and low temperature environment. In the future research, the experimental results can be used as the theoretical basis for potato planting.

不同贮藏温度下马铃薯幼苗的抗氧化活性

为了促进马铃薯幼苗的贮藏和生长，分析了马铃薯在不同贮藏温度下的抗氧化活性。比较了两种温度下马铃薯幼苗的抗氧化活性。另外，通过高温处理，分析了高温和常温对马铃薯幼苗生长表型和抗氧化系统生理指标的影响。根据不同温度下抗氧化指数的SOD活性的显着变化特征，筛选了马铃薯的SOD基因，并进行了生物信息学分析和基因表达分析。结果表明，高温抑制了马铃薯幼苗的抗氧化活性，影响了马铃薯幼苗的生长。在中低温环境下可以促进马铃薯幼苗的生长。在今后的研究中，实验结果可作为马铃薯种植的理论依据。
