摘　　要：着重研究了玉米青枯病病原禾生腐霉（PythiumgraminicolaSubram）和肿囊腐霉（P．inflatumMatth．）与其伴生病原禾谷镰刀菌（FusariumgramineariumSchw．）间代谢水平上的互作关系。结果表明：腐霉代谢产物对禾谷镰刀菌的生长有刺激作用，而禾谷镰刀菌代谢物对腐霉有明显的抑制作用；腐霉代谢产物对寄主的致萎能力比禾谷镰刀菌更强。This paper reports the interaction among Pythium graminicola,P. infiatum and Fusarium graminearium, which are pathogens of corn stalk rot. The results showed that the filtrates of the pythiums had a significant promoting effect on the growth of the fusarium;while the filtrates of the fusarium had a significant inhibiting effect on the pythiums.The filtrates of the pythiums had stronger wilting ability than that of the fusarium on the host seedling.
