Abstract: Allelopathy to Verticillium wilt（Verticillium dahllae）and the allelochemicals of the root exudates in the grafted eggplants with tomato as rootstock were studied. The ether extracts of the root exudates were detected by GC-MS. The results showed that a significant, strong disease resistance was found in grafted eggplants thean in own root plants. The root exudates of grafted eggplants had a significant suppression to the Verticillium wilt with the inhibitory rate at 15.43%. And the dentificantion of the allelochemicals in root exudates of grafted eggplants indicated that the categories and the relative contents were different from the own-root plants. The substances, such as carbazoles, azulenes, amines, fluorene and indenol, were be detected only in the grafted eggplants.
