【摘要】 禾谷类作物细菌性褐条病是我国局部地区禾谷类作物生产上的一种重要病害。通过对几种有关细菌的致病性,细菌学性状和DNA中G+C含量的比较研究,认为发生在我国的水稻细菌性褐条病是由Pseudomonas avenae Manns引起的,供试的黍、粟和稗细菌性褐条病菌都属于P.avenae;小麦上的细菌性褐条病是由Pseudo-monas syringae的一个致病变种引起的。此外,还从看麦娘上分离到一种国内尚无报道的水稻细菌性鞘褐腐病菌Pseudomonas fuscovaginae Tanil et al.。更多还原

【Abstract】 In recent years,bacterial stripe of cereai crops occurred seriousiy in pa-rts of China.39 isolates from infected rice and some other gramineous plantsand some related pathogenic bacteria were comparatively studied in pathoge-nicity,bacteriological charecteristics and G+C Mo1%of bacterial DNA.Theresults showed that the isolates from diseased rice,Setaria italica,Paniciummiliaceum,Echnochloa crugalli were the same as Pseudomonas avenae Manns.;the causal organism of the bacterial stripe of Alopecurus aequalis was ident-ified as Pseudomonas fuscovaginae Tanii et al;the bacterial brown stripe ofwheat was a new disease caused by a strian of Pseudomonas syringae.更多还原
