Abstract:

To identify the types of tomato wilt pathogens,select tomato rootstock varieties resistant to wilt disease,and explore the effects of resistant rootstocks on enzyme activity and the number of cultivable microorganisms in the rhizosphere.The results showed that the Fusarium oxysporum f.sp.lycopersici race 3 was the pathogen responsible for tomato wilt in Dingxing area,which has a large tomato cultivation area in Hebei Province.Two high resistance rootstock varieties(TMS150,Jinpeng No.8)and two disease resistant rootstock varieties(Ouzhen 006,CFH-27)were screened using the root injury soaking method.Overall,disease resistant varieties increased the activities of superoxide dismutase,peroxidase,polyphenol oxidase,and catalase,which were positively correlated with the abundance of potential beneficial microorganisms(Bacteria,Actinomycetes,Biocontrol bacteria,Nitrifying bacteria,Ammonifying bacteria,Azotobacter,and Cellulose degrading bacteria)in the rhizosphere soil and negatively correlated with the number of Fungi.This result provided a theoretical basis for the breeding of vegetable rootstock varieties with disease resistance and disease control.

Key words: Tomato wilt disease, Physiological race, Disease resistance, Enzyme activity, Microbial community
