摘　　要：本试验选用4种非致病性尖镰孢霉接种番茄幼苗,两天后接种番茄枯萎病菌,观察其诱导抗性效果。结果表明,以黄瓜尖镰孢(Fusarium oxysporum(schl) f.sp.cucumerinum Owen)的诱导抗性最好,防治效果为66.29%;其次是以栝楼尖镰孢(F.oxysporum Schlechtend)处理的,防效65.08%;辣椒尖镰孢(F.oxysporum Schl)和棉花尖镰孢(F.oxysporum Schl.f.sp.vesinfectum(Atk) Snyd.& Hans)防效分别为2.24%和19.09%,效果较低。Tomato seedlings were inoculated by root dipping with four non-pathogenic species of Fusarium and again with F. oxysporum f. sp. lycopersici two days later. The results showed that for induction of resistance to tomato wilt disease the orders were F. oxysporum f. sp. cucumerinum(66.29%)>F. oxysporum isolated from Trichosanthes(65.08%)>F. oxysporum f. sp. vesinfectum(19.09%)>F. oxysporum isolated from capsicum(2.24%).
