Abstract The induced eggplant resistance to Verticillium dahliae was tested by treating 5 exogenous chemical compounds.The results showed that all chemical compounds could reduce disease index.JA(100 μg?mL-1)was the most effective with ER of 48.5 %.The ER of 0.5 mmol?L-1 RI,5.0 mmol?L-1 RI and 0.50 mmol?L-1 VK3 were 27.0 %,20.6 % and 22.3 %,respectively.Furthermore,the experiment results indicated there were synergetic effect or inhibiting effect among the different exogenous chemical combinations.
