包含病原线虫的植物复合侵染病害的研究已逾１００年，对这种复合侵染病害的发现与验证是本世纪５０年代至７０年代间植物病理学的显著发展之一。植物病原学已从单一病原学发展至多重病原学。本文就重要的复合侵染病害及其病原的协同作用方式和协同作用机制等方面的研究进展作了评述。展望２１世纪，相信我国植物病理学者将会越来越多地关注植物复合侵染病害问题，从而推动该领域的研究不断深入与发展。 More than 100 years have passed since the study of plant complex infestations involving pathogenic nematodes. The discovery and validation of this composite infestation has been one of the significant advances in plant pathology from the 1950s to the 1970s. Phytopathology has evolved from a single etiology to multiple etiology. In this paper, the progress of the research on synergistic action and synergistic mechanism of important complex diseases and their pathogens were reviewed. Looking forward to the 21st century, it is believed that plant pathologists in our country will pay more and more attention to the problem of plant complex infection diseases, so as to promote the research in this field.
