不同抗性向日葵品种感染菌核病后，抗病品种叶片中 PAL、POD、CAT、SOD 等4种酶活性的增幅均大于感病品种，而抗、感品种 PPO 活性均呈下降趋势，但2个品种的 PPO 活性差异不显著。
不同抗性嚮日葵品種感染菌覈病後，抗病品種葉片中 PAL、POD、CAT、SOD 等4種酶活性的增幅均大于感病品種，而抗、感品種 PPO 活性均呈下降趨勢，但2箇品種的 PPO 活性差異不顯著。
불동항성향일규품충감염균핵병후，항병품충협편중 PAL、POD、CAT、SOD 등4충매활성적증폭균대우감병품충，이항、감품충 PPO 활성균정하강추세，단2개품충적 PPO 활성차이불현저。
After the resistant variety of sunflower leaves were infected with S.sclerotiorum, the increase of the activities of 4 enzymes, including PAL, POD, CAT, SOD in the leaves of resistant variety were all significantly higher than those of the susceptible variety, but the PPO activities of the resistant and susceptible varieties both had a decreasing tendency, but the difference between PPO activities of the 2 varieties was not very significant.
