Abstract

The dynamic changes in POD,PPO,PAL,SOD in leaves of different cucumber cultivars were studied after they were infected by fusarium oxysporum at seeding stage.The results showed that the enzyme activities were raised following the days past when they were infected by fusarium oxysporum.but POD,PPO,PAL,SOD enzyme activities of resistant varieties was higher than the susceptible ones.These reactions illustrate the four enzymes play an important role after they were infected by fusarium oxysporum at seeding stage.
