小麦条锈病由小麦条锈菌(Puccinia striiformisWestend.)引起,该病害发生范围广、流行频率高、危害损失重。小麦条锈菌侵染与繁殖均需要较低温度,过去研究表明,条锈菌在夏季最热旬均温23℃以下地区才能越夏[1]。近年调查研究发现,小麦条锈菌的越夏海拔下限明显降低,病菌在夏季最热旬的旬均温超过23℃的地区也能越夏。研究
Wheat stripe rust is caused by Puccinia striiformisWestend. It has a wide range of occurrence, high prevalence and heavy damage. Wheat stripe rust infection and reproduction are required lower temperatures, the past studies have shown that stripe rust in the hottest summer average temperature below 23 ℃ in summer can be [1]. In recent years, the survey found that the lower limit of summer wheat over the summer wheat stripe rust significantly reduced, the bacteria in the hottest period of ten days average temperature more than 23 ℃ in summer can be more. the study
