Abstract:
The changes of active oxygen species and some enzymes in Grifola umbellata induced by Armillaria mellea elicitor were studied.The results showed that active oxygen species appeared in both mycelia and sclerotia of G.umbellata after treated with A.mellea.There were two phases of active oxygen production upon addition of A.mellea elicitor.Phase I occured at 10 minute after addition of A.mellea elicitor.Phase Ⅱ occurred about 90 minute.The changes of some enzyme activity were also studied in this paper.Compared with control,the A.mellea elicitor could reduce the activity of superoxide dismutase and peroxidase.The catalase activity changed only little.The phenylanine ammonia lyase activity declined in the early stages and then increased in the late stages.
