作者在1980～1981年,通过灰飞虱(Laodelphax Striatellus Fallen)接种,试测了36属70种禾本科植物和棉花等9种双子叶植物。根据病状和回接结果,57种禾本科植物感染,所试双子叶植物均不感染。寄主植物有高梁、谷子、水稻、玉米、大麦、燕麦、黑麦、小黑麦和小麦属的20个种,以及马唐、稗草、金狗尾、画眉等28种禾草。我国玉米粗缩病的病毒寄主植物及其病状反应与玉米粗缩病毒(MRDV)和水稻黑条矮缩病毒(RBSDV)相似,但有不同。主要区别是我国玉米粗缩病的病毒侵染高梁。高梁感染后明显矮化,叶色暗绿,叶脉间发生密集的平行透明条点,叶背和叶鞘的脉上产生一些蜡泪状隆起,以及心叶叶缘缺蚀。
In 1980-1981, nine dicotyledons of 36 species, 70 species of gramineous plants and cotton, were inoculated by Laodelphax striatellus Fallen. According to the symptoms and the results of the reconnection, 57 species of gramineous plants were infected and none of the tested dicotyledons were infected. Host plants are sorghum, millet, rice, corn, barley, oats, rye, triticale and wheat genus 20 species, and crabgrass, barnyardgrass, golden dog tail, thrush and other 28 kinds of grass. The host plants and their pathogenic responses to maize roughing virus in China are similar but different from MRDV and RBSDV. The main difference is that China’s maize sicken virus infects sorghum. Sorghum significantly dwarf infection, dark green leaf color, dense parallel lines between the veins occurred, leaf back and leaf sheath pulse produced some wax tear-like uplift, as well as leaf edge margin erosion.
