Antioxidant Activity of Potato Seedlings at Different Storage Temperatures

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.
