Cultural characteristics of pathogenic Ralstonia solanacearum from Pogostemon cablin(Blanco)Benth
摘要
Abstract
Objective To study on the cultural characteristics of Ralstonia solanacearum from Pogostemon cablin( Blanco) Benth. , which might contribute to the effective control and prevention over the disease.Methods The bacterial growth was determined by A600 of bacterial suspension. Effects of temperature and pH on the multiplication of R. solanacearum, as well as the utilization of carbon and nitrogen nutrient sources were investigated. Results The optimum temperature and pH for bacterial growth was 33 - 35 ℃ and 6. 5, respectively. R. solanacearum preferred fructose, maltose, sucrose and sorbitolum among the 9 tested carbon sources to glucose. Organic nitrogens were more favorable for R. solanacearum than the inorangic ones, of which Yeast extract promoted bacterial proliferation remarkably while KNO3 was suppressive. Conclusion The cultural characteristics of R. solanacearum were described , which served for the prevention of R. solanacearum in P. cablin.关键词
