真菌在侵染小麦过程中,不同真菌之间可能发生协合作用、拮抗作用或中性作用.研究它们之间的相互作用不仅具有理论意义,而且对其防治、抗病育种及杀菌剂的筛选等方面具有重要作用.本文简要介绍世界上这方面主要的研究成果.协合作用病原真菌在致病过程中,一种病原菌能锈发或促进另一种病原菌的致病性,这种现象称为病害间的协合作用。这方面报导不多,主要有3例.小麦叶锈病与小麦白粉病美国的 Johnson 报导,某些抗小麦叶锈病的品种,被白粉病侵染后,失去对叶锈病的抗性。他发现,抗叶锈9号生理小种
Fungal fungi may have synergistic, antagonistic or neutral effects among different fungi during the process of wheat fungus infection.It is not only of theoretical significance to study the interaction between fungi, but also its control, disease-resistant breeding and screening of fungicides Etc .. This article briefly introduces the main research results in this field in the world Synergistic effect Pathogenic fungi in the pathogenic process, a pathogen can rust or promote the pathogenicity of another pathogen, this phenomenon that Synergistic effect between diseases. Little is reported in this area, and there are three main cases.Polypae leaf rust and wheat powdery mildewThe United States of Johnson reported that some varieties of wheat leaf rust resistance, after being infected by powdery mildew, lost its resistance to leaf rust. He found that the leaf rust No. 9 physiological races
