| 摘 要： | 采用番茄为砧木嫁接茄子，研究了嫁接对茄子黄萎病的化感作用，并对嫁接茄子根系分泌物中的化感物质进行了GC-MS检测。结果表明，与自根茄相比，嫁接茄子田间表现出明显的抗病性；其根系分泌物能够抑制病原菌的生长，抑制率达15.43%。进一步对各处理根系分泌物进行检测，嫁接茄根系分泌物中物质种类和相对含量与对照相比均有变化。在嫁接茄子根系分泌物中检测出特征性化学物质：咔唑类、胺类、萸类、芴类、酮类、茚醇类、腈类，烃类和酯类物质相对含量增加，而苯类、茚类物质相对含量降低。

| 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. |
