本文综述了我国在玉米茎基腐病和穗腐病病原学、致病性和寄主抗性机制与综合治理的研究进展。深入探讨了以往我国学者关于引起茎基腐病病原学的不同观点。根据2种病害的病原镰孢菌在可溶性蛋白质、血清学、同功酶和DNA等不同水平的多态性分析,镰孢菌在寄主根和茎组织内侵染过程示踪和孢子捕捉试验结果,重点讨论了2种镰孢菌病害在病原学侵染规律方面的相互关系,概述了2种病害寄主抗性生理生化机理、抗性遗传和以生物防治为核心的综合治理措施研究进展。
This review summarizes the progress in the research on etiopathogeny, pathogenicity and host resistance mechanism and integrated management of corn stem-base rots and ear rots in China. In-depth discussion of the previous scholars on the cause of stem rot etiology point of view. According to different levels of soluble protein, serology, isoenzyme and DNA polymorphism analysis of Fusarium pathogenicity of two kinds of disease, tracer and spore catching test results of Fusarium infection process in the host root and stem tissues The relationship between the pathogen infection rules of two kinds of Fusarium pathogens and the pathophysiology of the two disease hosts were summarized. The progress of the research on the physiological and biochemical mechanism of resistance of the two disease hosts, the genetic inheritance of resistance and the integrated control measures with biological control as the core were summarized.
