Fecha de publicación: 17/12/2021 Fuente: WIPO "processing tomato" The invention discloses a growth-promoting bacterium Paenarthrobacter nitroguajalicusD8 which can mediate processed tomatoes to generate induced systematic resistance and has a relatively good disease prevention effect on tomato early blight, gray mold and bacterial wilt, the bacterium is screened in green bean plant rhizosphere soil in a green bean field in a farm in West Mountain of Wujiang Mountain in Xinjiang, the bacterium is known to be a novel bacterium similar to Paenarthrobacter nitroguajalicus through classification and systematic identification and analysis, a Paenarthrobacter nitroguajalicus D8 growth-promoting microbial inoculum is prepared by using a liquid fermentation technology, tomato seeds are treated and processed, such that the bud length, the germination rate and the germination potential of the tomato seeds are significantly increased, and the tomato root length, the fresh weight and the plant height are significantly improved. The bacterial liquid of the strain D8 can obviously increase the jasmonic acid content of the processed tomatoes and maintain the jasmonic acid content for a certain time, so that the processed tomatoes generate systematic resistance, and the disease resistance of the processed tomatoes to three pathogenic bacteria is enhanced. The novel growth-promoting microbial inoculum provided by the invention is used for processing tomato epidemic situation prevention and control, is green, environment-friendly and low in cost, and has wide application value for expanding the technical field of application of microbial growth-promoting bacteria strains.
