摘要
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。
During 4 years of 1992-1995.105 fungal strains were isolated maize stalk rot samples in Jiangsu Province. Results of pathogenicity tests showed that Pythium inflation, P. graminicola , Fusarium monili forme var. zhejiangensis, F. monili forme var. intermedium, F. monili forme var. subglutinanst, F. graminearum, F. sporotrichioides var. chlamydosporum ,F. oxysporum var. redolens,F. sambucimon,F. solani and F. semitectum were the pathogens of stalk rot of corn,of them F. moniliforme and Pythium spp. were main pathogens.
