| Abstract: | The activity of phenylalamine ammonia-lyase,peroxidase and polyphenol-oxidase in leaves of resistant and susceptable wheat varieties to powdery mildew were determind in earing-stage.The results showed that the activity of three kinds of enzymes were all higher in powdery mildew resistant varieties than that of susceptable varieties.The activity of enzymes has significent negtive correlation with disease index.Improvement of various kinds of enzymes activity could promote the formation of pathogen-resistant materials and was a kind of active protection reaction. |
