| 摘 要： | 以从美国番茄遗传资源中心引进的3个抗青枯病番茄材料LA2701、LA3202和LA3526为砧木，以番茄栽培品种早冠30为接穗，采用劈接法进行嫁接试验。对嫁接苗和自嫁苗利用伤根灌注法接种青枯病菌，3个嫁接砧木均明显提高了番茄的抗青枯病水平。对嫁接植株活体内青枯病菌数量进行调查，结果表明抗性砧木有效地抑制了青枯病菌在体内的增殖。

| Abstract: | Grafting analysis was carried out using three tomato(Lycopersicon esculentum Mill.)lines introduced from Tomato Genetics Resource Center USA(TGRC):LA2701,LA3202 and LA3526 with high resistance to bacterial wilt as rootstocks and'Zaoguan 30'as cions.Grafted plants were inoculated with Ralstonia solanacearum and bacterial wilt resistance was investigated.Results indicated that the three tomato lines could improve the bacterial wilt resistance obviously.Ralstonia solanacearum in vivo analysis indicated the gra... |
