Abstract: Trichoderma harziaiarum plays a role of antagonic ability to pathogenic micr obes and of inducing plant to produce a resistivity of disease. In this paper, afte r the rice was sprinkled by zymolytic liquid of Trichoderma harziaiarum, the changes on the activities and isoenzymes of polyphenol oxidase (PPO) and pe roxidase (POD) were investigated. The results indicated that Trichoderma harz iarum could increase the activities of PPO and POD and produce new pattern of isoe nzymes; the different concentration of zymotic liquid had a different effects on the PPO and POD that were caused by the liquid; the 50 times diluted liquid had a greatly positive relation to the POD activity; and the higher concentration o f the liquid had a tendency that made the PPO activity inhibition and then incre ase, which denoted that the liquid took a scheduled adjustment play of the PPO a ctivity.
