This indicates that peonies can reduce the damage of reactive oxygen species by enhancing the activities of antioxidant enzymes under 3d heat stress, but the activities of APX and CAT still show an increasing trend, while the activities of SOD and POD decreased under long-term (5d–7d) high temperature stress, which is different from the results of previous studies [ 17 , 42 ], indicating that different antioxidant enzymes were sensitive to different temperatures and activated at different temperature ranges, and that activation occurs at different temperature ranges [ 43 ].
