摘要
1988—1989年采集山东大豆根腐病标样553个,经分离接种证明,致病菌有茄病镰刀菌[Fusarium solani(Mart.)Sacc.]、尖孢镰刀菌(F.oxysporum Schl.)和木贼镰刀菌[F.equiseti(Corda)Sacc.]三种,以茄病镰刀菌的分离频率最高,致病力最强,为主要致病菌。并对其培养特性、形态特征、寄主范围和光照、温度及pH对生长的影响进行了研究,根据这些研究结果,将大豆根腐病主要致病菌定名为茄病镰刀菌大豆专化型[Fusarium solani(Mart.)Sacc.f.sp.glycines Li et Luo],本专化型过去没有报告。
Five hundred and fifty-three isolates of soybean root rot,collected from7 counties in Shandong province,were studied and demonstrated that theybelong to Fusarium solani,F.oxysporum and F.equiseti during 1987—1988.Among them,F.solani was of the highest frequency and incidence.This iso-late was designated as Fusarium solai(Mart.) Sacc.f.sp.glycines Li & Luo.a specialized form of Fusarium solani (Mart.)Sacc.,based on its cultural,morphological and pathogenic characters.
