作者于1992～1995年,从江苏省玉米主产区采集的玉米茎腐病标样中分离获得105个菌株,经鉴定,致病菌种类有肿囊腐霉(Pythium inflatum)、禾生腐霉(P.graminicola)、串珠镰孢浙江变种(Fusarium moniliforme var.zhejiangensis)、串珠镰孢中间变种(F.moniliforme var.intermedium)、串珠镰孢胶孢变种(F.moniliforme var.subglutinans)、禾谷镰孢(F.graminearum)、拟枝孢镰孢厚膜变种(F.sporotrichioides var.chlamydosporum)、尖孢镰孢芬芳变种(F.oxysporum var.redolens)、接骨木镰孢(F.sambucinum)、茄病镰孢(F.solani)、半裸镰孢(F.semitectum)等11个种或变种。其中串珠镰孢浙江变种出现频率最高,占44.8％,肿囊腐霉和禾生腐霉致病力最强,这两类菌是江苏玉米茎腐病主要病原。
From 1992 to 1995, 105 strains were isolated from corn stalk rot samples collected from the main corn producing areas in Jiangsu Province. The strains were identified as Pythium inflatum, P. graminicola, Fusarium moniliforme var. Zhejiangensis, F. moniliforme var. Intermedium, F. moniliforme var. Subglutinans, F. graminearum, F. sporotrichioides var. Chlamydosporum, F. oxysporum var. Redolens, F. sambucinum, Fusarium spp., F. semitectum, and so on. Among them, Fusarium moniliforme Zhejiang had the highest frequency of occurrence, accounting for 44.8%. The pathogenicity of Pythium cyst and Pythium ramosum was the strongest. These two types of bacteria were the main pathogen of stalk rot in Jiangsu.
