Study on the Physiological and Biochemical Characteristics of Pepper after Inoculation the Phytophthora capsici

In order to study the physiological and biochemical characteristics of pepper after inoculation the Phytophthora capsici,the changes of activity about phenylalanine ammonia lyase(PAL),polyphenol oxidase(PPO),β-1,3-Glucanase and chitinase were mensurated.The results showed that the changes of these protective enzymes'activities were remarkable difference between different resistance pepper lines.There was a positive correlation between the activities of phenylalanine ammonia lyase(PAL),polyphenol oxidase(PPO),β-1,3-Glucanase and chitinase and the pepper resistance to Phytophthora capsici.
