【摘要】 本文报道了发生于甘肃省敦煌县的玉米条纹矮缩病,是由灰飞虱传播的一种病毒病害。对病叶进行包埋切片和抽提纯化、电子显微镜观察,结果在病叶组织细胞内或抽提纯化汁液中,均可见到大量的弹状病毒质粒。切片中质粒大小为43～64×150～220毫微米,抽提纯化的质粒大小为70～80×200～250毫微米。从弹状病毒质粒大小,既不同于小麦丛矮病毒,也不同于玉米花叶病毒的弹状质粒,可能是一种新的侵染玉米的弹状病毒。更多还原

【Abstract】 The maize streak dwarf disease which caused a lot of damage to the maize crop in Tuenhuang, Kansu province, was transmitted by the plant hopper Laodelphax striatellus Fallen. In the ultra-thin sections and in the extracts of the leaf cells of the diseased but not healthy plants a new rhabdo virus measuring 43～64×150～220nm (in sections) or 70～80×200～250nm(in extraots) was detected. The virus particles were seen to be enwrapped both inbetween the inner and outer nuclear membrane and in the endoplasmic reticula.更多还原
