Abstract

Abstract: Apium graveolens L. is an important feature of Inner Mongolia cold cool vegetables.Shangdu County,as one of the main producing region,root rot in recent years has become an important factor restricting the development of the industry.This study used tissue separation,morphology and molecular biology method combining the separate identification of the celery root rot pathogens of Shangdu County,through the petiole and root that are inoculated to determine the pathogenic strains.The results show that the separation of the four strains XY1,QC-3,QC-5 and 2QC-3 were pathogenic strains of XY1,QC-5 for Fusarium oxysporum,strain QC-3,2 QC-3 for Fusarium solani,and complete law of Koch’s appraisal.It is clear that Fusarium oxysporum and Fusarium solani are the main pathogenic bacteria causing root rot of Apium graveolens L. in Shangdu County.

Key words: Apium graveolens L., Root rot, Fusarium oxysporum, Fusarium solani
