Relationship between incidence of Verticillium wilt on eggplant and nematode population in the rhizosphere soil
茄子黄萎病发病程度与根际土壤线虫种群数量的关系研究

The results show that the relationship between nematod e population in field of eggplant and the incidence of Verticillium wi lt on eggp lant is significant; the numbers of nematode in rhizosphere of serious s ymptom o n eggplants are more than those of light disease eggplants and health p lants; th e nematodes in root of the serious disease plants are more dense than t hose of l ight disease and health ones, but there are no differences between rhizosp here a nd out rhizosphere of eggplant field; the incidence of Verticillium wilt on egg plant is much seriously inoculated by the mixture of the pathogen and nematodes than only by the fungus, and the more nematodes are inoculated, the mu ch serious ly the disease is; the nematodes population inoculated by the mixture is more th an that only by the fungus; the parasitical nematodes species are Tyle nchu, Prathylenchus, Tylenchornychus and Aphelenchoidae.
