| 摘 要： | 八十年代初期,内蒙岭北地区春小麦大面积发病,严重减产.病株矮化丛生,叶片有黄绿相间条纹.试验证明灰飞虱(laodelphax striaxtellus Fallen)为主要传播媒介.病株汁液经粗提纯,电镜观察到杆状病毒质粒和病毒核衣壳螺旋状结构,并与小麦丛矮病毒抗血清呈阳性反应.因此认为侵染内蒙岭北地区春小麦的病原是小麦丛矮病毒(WRSV).

| Abstract: | In the beginning years of 1980s , the spring wheat occured a disease widespread and rebuced yield seriously in the Lingber district, Inner Mongolia. Plants are severe -ly dwarfed and produce abundant tillers with yellow and green variegated narrow strips on the leaves. The experimental results indicated that planthopper laodelphax strie-tellu is the main main vector.Through the electron microscopic study, it showed as bullet-shaped particles and its nucleocapsid with helicoid construction. The serological reaction is positive with WRSV. Thus it is proved that the pathgen of this disease of spring wheat is the virus of WRSV. |
