Inducing Defense Enzyme Activity on Eggplant Root by Trichoderrna viride T12

Defense enzymes in root of eggplant seedling were examined treating with conidiospores and chlamydospores of T12 respectively.The results showed the activities of defense enzymes in eggplant root such as phenylalanine ammonia lyase,peroxidase catalase,superoxidedimutase were changed by conidiospores and chlamydospores of T12.It indicated that the production of phytoalexin might be involved to resistant eggplant verticillum wilt.Inducing function of resistant variety were obvious than susceptibility variety,of chlamydospores were better than conidiospores.
