摘　　要：以托鲁巴姆、本地野生刺茄和赤茄作砧木,长丰二号红茄、农夫长茄为接穗,探讨不同砧木嫁接对茄子生长及抗褐纹病的影响。经过春夏秋三季共3茬的试验,结果表明:嫁接可提高茄子对褐纹病的抗性,尤其春季最为显著;在生长方面,嫁接能延长茄子采收期,使总产量增加12%以上。茄子嫁接苗的抗性主要由取决于砧木,而长势及产量多由接穗决定,因此,选用合适的砧木和接穗做嫁接,能增强茄子的抗病抗逆性,提高茄子的产量。In this study,with torubam,local wild stab eggplant and red eggplant as rootstocks,Changfeng Ⅱ red eggplant and farmer eggplant as scion,the effects of different rootstocks grafting on the growth and phomopsis rot resistance of eggplant（Solanum melongena L.） were investigated.After the spring,summer and autumn of 3 trials,results showed that grafting could improve disease resistance to eggplant phomopsis rot,particularly significant in spring.In terms of growth,the harvest period could be extended,and the production increased by more than 12%.Resistance of eggplant grafted mainly depends on rootstocks,than the growth and production determined by the scion,so,the appropriate choice of rootstock and scion can improve disease resistance and increase production of eggplant（Solanum melongena L.）.
