摘要
从1981年至1988年,研究了8种镰刀菌诱发感病棉株对棉枯萎病菌抗性的效应和诱导接种与激发接种间有效间隔天数。结果表明:参试的8种镰刀菌中,半裸镰刀菌(Fusarium scmitectum),黄色镰刀菌(F. culmorum),接骨木镰刀菌(F. sambucinum),拟枝孢镰刀菌(F. sporotrichioldes)诱发的棉株可明显提高对棉枯萎菌的抗性。而芬芳镰刀菌(F. redolens),尖孢镰刀菌(F. oxysporum)诱导的棉株其病指则高于对照。二次接种的最佳间隔天数为5天。
The initial inoculation with Fusarium semitectum, F.culmorum, F.sambucinum, F.sporoirichioides reduced the mean disease index of diseased plants (by Challenge inoculum) significantly.It suggested that the above four Fusarium species were effective inducers.The level of induced resistance was affected by the time interval between initial and challenge inoculation considerably, the best induction efficiency appeared to be 5 days interval.
