| 摘 要： | 通过从云南省主要产烟区收集到的45个烟草野火病菌菌株在15个供试烟草品种上的接种试验研究,筛选到一套烟草野火病菌生理小种鉴别寄主体系.同时,以发病率作为抗感划分标准,可将供试菌株划分为4个生理小种(即生理小种Ⅰ、Ⅱ、Ⅲ、Ⅳ).

| Abstract: | Total 45 isolates of Pseudomonas syringae pv. tabaci collected from Yunnan province were inoculated on the fifteen tobacco cultivars,a set of differential host system was selected,by means of 20% incidence as the limit action between resistance and susceptible,forty five isolates of P.s. pv. tabaci were divided into four races(i.e.physiological raceⅠ、Ⅱ、Ⅲ、Ⅳ). |
