摘　　要：以亲和番茄、亲家番茄、本地野生刺茄作砧木,以达尔文番茄、绿樱1号樱桃番茄为接穗,探讨不同砧木嫁接对番茄生长发育及抗青枯病的影响。结果表明,嫁接可显著提高番茄抗青枯病的能力;在生长发育方面,以本地野生刺茄做砧木与两个接穗的亲和力明显不如亲和、亲家两个番茄砧木,随着生长,本地野生刺茄与两个接穗的不亲和现象越明显,表现在嫁接部位砧木的茎粗显著小于接穗,植株矮化、生理性早衰,果实变小;在产量方面,用亲和、亲家番茄做砧木嫁接,能延长番茄采收期,增加番茄的结果数,提高番茄的单果重,使总产量增加15%以上。In this study, with Qinhe tomato, Qinjia tomato and local wild stab eggplant as rootstocks, Darwin tomato and green cherry 1 tomato as scions, the effects of different rootstocks grafting on the growth and bacterial wilt resistance of tomato（Lycopersicon esculentum Mill.） were in vestigeted. The results showed that grafting could improve disease resistance to tomato bacterial wilt. In terms of growth and development, local wild stab eggplant with the two scions had poorer affinity, with the growth, the rootstock stem diameter at grafted parts was significantly smaller than the scion, physiological premature appeared and fruitbecome smaller. In terms of production, using Qinhe tomato and Qinjia tomato as rootstocks, could extend the tomato harvest, increase the tomatoes number, improve tomato fruit weight, so that the total output increased by more than 15%.
