对盆栽水稻采用针刺、喷雾、盆水等不同方法接种水稻细菌性条斑病病菌后 ,检测稻株发病和盆水中的噬菌体 ,结果表明 :未接种稻细条病菌的处理中 ,无稻株发病 ,盆水中也未测到噬菌体 ;3种接种处理均可引致稻株发病 ,并先后在其盆水中检测到噬菌体 ,说明噬菌体与致病菌有密切的伴随关系。在采用叶面喷雾和盆水接种稻白叶枯自然组合菌株B 1和单细胞系菌株Ⅳ 16试验中 ,B 1处理后能引起稻株发病 ,且在盆水中测到噬菌体 ;而Ⅳ 16处理后虽引起稻株发病 ,但盆水中无噬菌体 ,结果表明 :在人工接种条件下植物病原细菌噬菌体是由病菌中的溶原细胞传带而来的
The potted rice was inoculated with different pathogen of bacterial leaf streak by using acupuncture, spraying and potting water to detect the incidence of the disease and the phage in the potting water. The results showed that in the uninoculated rice bacterial pathogen, , And no phage was detected in the pellet water. The three kinds of inoculation treatments could cause the rice plant disease, and phage was detected in its basin water successively, indicating that bacteriophages and pathogenic bacteria are closely related. In foliar spray and potted water inoculation with the natural combination strain B 1 and the single cell strain Ⅳ 16 inoculated with foliar spray, B 1 treatment could cause the rice plant disease and detect the phage in the pellet water; Although it caused the rice plant disease, the bacteriophages in the water showed no phage. The results showed that under the conditions of artificial inoculation, the phage of the plant pathogenic bacterium was carried by the lysogenic cells in the bacteria
