从湖南18个县(市)采集的水稻细条病病叶中分离出24个噬菌体分离株,用7种不同的植物病原细菌进行了专化性测定,结果表明供测的噬菌体只能侵染水稻细条菌;用来自湖南、广东、广西、福建及四川的水稻细条菌90个菌株对噬菌体敏感性进行测定,认为可将供试菌株分为3类共23个溶菌型.并提出了提高噬菌体法检测种子带菌效果的建议. Twenty-four phage isolates were isolated from the leaves of rice stripe disease collected from 18 counties in Hunan Province. Seven different kinds of phytopathogenic bacteria were used for the specificity test. The results showed that the phage used for the measurement could only infect rice Bacteroides sp.The sensitivity of 90 strains of rice stromal bacteria from Hunan, Guangdong, Guangxi, Fujian and Sichuan was determined, and the results showed that the strains could be divided into three classes of 23 bacteriolytic strains, Suggestion to detect the effect of seed carrier.
