Abstract:
Trichoderma koningii was used as the test material,different concentrations of honokiol were used to treat T.koningii to study the effects of honokiol on mycelia growth,morphological structure and antioxidant enzyme activity of T.koningii,in order to provide reference for green prevention and control of Phallus rubrovolvatus rot disease.The results showed that honokiol had significant antibacterial activity against T.koningii，and its EC50 value was 6.252 μg·mL-1.After treatment with honokiol，the mycelial morphology of T.koningii showed significant changes.The surface of the mycelium showed irregular shrinkage and distortion，there was obvious plasmic wall separation，organelle damage，and there was a large area of blank space in the cell.In addition，the physiological system was disturbed，superoxide dismutase (SOD) activity increased，catalase (CAT) and peroxidase (POD) activity decreased，resulted in excessive reactive oxygen species accumulation，cell damage,and mycelial growth was inhibited.In conclusion，honokiol could significantly inhibit the growth of T.koningii，and could be used as green prevention and control drugs for Phallus rubrovolvatus rot disease in the future.
