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).
In the early 1980s, large area of spring wheat in Lingnan northern Inner Mongolia was severely cut off and its yield was seriously reduced. The diseased plants dwarfed with yellow-green fringes, and the laodelphax striaxtellus fallen was the main vector. Purified and electron microscopy showed the helical structure of the baculovirus plasmid and the nucleocapsid of the virus and was positive with anther of wheat cluster stunt virus so that the pathogen of spring wheat infected with northern Inner Mongolia Ridge was wheat cluster stunt virus (WRSV).
