[目的]筛选适合番茄嫁接的砧木.[方法]比较3个砧木品种嫁接番茄苗及自根苗在抗病性、亲和性、长势、产量、主要果实性状等方面的优势.[结果]番茄嫁接茴较自根苗在抗青枯病能力及产量上表现出极大的优势,自根苗青枯病平均发病率为91.33％,嫁接苗青枯病平均发病率0 ～0.67％,嫁接苗产量较自根苗产量极显著增加403.06％～673.39％.头王台木与接穗嫁接亲和性及共生亲和性较好,其嫁接苗嫁接成活率较高,抗青枯病能力强,坐果率、单株果数、单果重、产量等经济性状优良,适宜作为番茄嫁接砧木进一步示范推广.[结论]该研究可为嫁接番茄的示范推广提供科学依据.%[Objective] The stock for tomato grafting was screened.[Method] Three rootstocks grafted tomato seedlings and self-rooted seedling were compared in disease resistance,graft compatibility,growth vigor,yield,fruit characters and other advantages.[Result] Grafted tomato seedlings had greater advantage than self-rooted seedling in resistance to bacterial wilt and yield,the average incidence of bacterial wilt for self-rooted seedling was 91.33％ and the grafted seedling was 0 ～ 0.67％,yield of grafted seedling was significantly increased by 403.06％ ～ 673.39％ than self-rooted seedling.The Touwangtaimu rootstock and scion had better graft compatibility and symbiotic affinity,its grafting survival rate was higher,the ability of resistant to bacterial wilt was stronger,its economic traits were better concluding the bearing fruit rate,fruit numbers,fruit weight,yield.Therefore,the Touwangtaimu rootstock was considered suitable for further testing to demonstrate and promote the grafting for tomato cultivation.[Conclusion]The study can provide scientific basis for the demonstration and extension of grafted tomato.
