radopholus similis(Cobb 1893) Thorne(1949) is a destructive migratory endoparasitic plant nematode. In this study,the pathogenic process of r. similis infection in Nicotiana benthamiana(tobacco) was studied using quartz sand culture in laboratory. The results showed that r. similis mainly parasitised the root cortex, leading to cortical cell decomposition and tissue decay. We optimised the inoculation conditions to establish a method for determining the pathogenicity of r. similis as follows:(1) a glass culture tube was filled with quartz sand(about 1/3 of the height) and sterilised twice;(2) 20-day-old N. benthamiana seedlings were transplanted into test tubes and cultivated for 10 days at(25±1)°C;(3) r. similis female nematodes were inoculated in the root rhizosphere at a rate of 150 nematodes per plant;(4) the number of nematodes, disease severity, and growth of the plant at 30 days post-inoculation(dpi) were determined. The pathogenicity of eight r. similis populations from different hosts was determined, which proved the feasibility of this method.

Dioxin is a general designation of polychlorinated dibenzo-p-dioxins （pCDDs） and polychlorinated dibenzofurans （pCDFs）. They are two series of tricyclic, almost planar, aromatic compounds, which are composed of 75 pCDD and 135 pCDF congeners,respectively. Among them, the most toxic congener is 2, 3, 7, 8-TCDD, with the suggested permissible level for human 10×10p>-9p>mg/（kg·d）p>-1p>. The environmental scientists have expressed much concern over these compounds since the 1980s. Chlorine-containing
