Significant increasing in cellulase and pectinase activity were observed in response to infection with Hendersonula toruloidea and Phiaoacremonium aleophillium in apricot trees comparing with uninfected trees. Pectinase highest activity was recorded at the first week after inoculation with H. toruloidea (1.76 unit/g f.w.), while cellulase highest activity was recorded after two weeks of inoculation with P. aleophillium (6.49 unit/g f.w.). Peroxidase and polypolyphenol oxidase activity were significantly increased after inoculation with H. toruloidea and P. aleophillium, Peroxidase highest activity was recorded after 48 h of inoculation with H. toruloidea (1.77 unit/g f.w.), while polypolyphenol oxidase highest activity was recorded after two weeks of inoculation with P. aleophillium (3.33 unit/g f.w.). The result also showed that total phenol contents was significantly increased as a result to inoculation with H. toruloidea and P. aleophillium, highest total phenol contents was recorded after 48 h of inoculation with H. toruloidea ( 1.61 mg/g f.w. ). 展开更多
