Abstract:
Using the herbaceous Paeonia lactiflora seeds as the test materials，the dynamic changes of the activity of antioxidant enzymes in the process of its germination were determined,the relationship between the Paeonia lactiflora seeds germination process and the activity of antioxidant enzymes were analyzed and explored.The results showed that superoxide dismutase (SOD) activity and peroxidase (POD) activity were negatively correlated with seed germination，catalase (CAT) activity and germination were positively correlated and in the rising state slowly.Paeonia lactiflora seed began to germinate in about 12 hours’ imbibition，and SOD worked earlier than POD and CAT.
