水稻类普矮病在闽西、闽北和闽南均有发生,其为害性不可忽视。病害症状因品种不同而表现为两种基本类型——普矮型和草丛型。将类普矮病和普矮病接种在同一稻苗上.可先后产生各自的症状。病害仅能通过黑尾叶蝉和二点黑尾叶蝉传播。电光叶蝉、白翅叶蝉、褐飞虱和缢管蚜均不传病。病土、病种子和病株汁液也不能传病。对黑尾叶蝉的一些传病特性作过测定。带毒的黑尾叶蝉能终身传毒,但有明显的间歇现象,不经卵传播。将带有普矮病毒和类普矮病毒的黑尾叶蝉分别接种在健康的稗草上。结果证明稗草很容易感染普矮病毒,而不能感染类普矮病。类普矮病毒质粒球状.与普矮病毒抗血清无免疫反应。根据病害的传播方式、症状表现和野生寄主——稗草的反应,以及病毒的形状和血清反应,初步认为水稻类普矮病(Rice dwarf-like disease)是禾谷类作物上的一种新的病毒病。
Rice dwarf disease in Fujian Province, Fujian and northern Fujian have occurred, its harmfulness can not be ignored. Disease symptoms due to different varieties showed two basic types - Pu and grass type. Vaccinia vulgaris and Pu short diseases will be inoculated on the same rice seedlings can have their own symptoms. Diseases can only be transmitted by the black-tailed leafhopper and the two-tailed leafhopper. Electric light leafhopper, white wing leafhopper, brown planthopper and aphid are not transmitted disease. Sick soil, sick seeds and diseased juice can not be transmitted disease. Some of the transmission characteristics of the black leafhopper were measured. Poisoned leafhopper can life-long poisoning, but there is a clear intermittent phenomenon, without egg transmission. Inoculated on healthy barnyardgrass were black leafhopper with common stunt virus and common stunt virus. The results show that barnyard grass is very susceptible to PUFV, and can not be infected with the class of PU dwarf. Class Dwarf virus plasmid globular.With the total short virus antiserum no immune response. According to the mode of transmission of the disease, the symptoms and the reaction of the wild host, barnyardgrass, and the shape of the virus and the reaction of the serum, rice dwarf-like disease is preliminarily thought to be a new type of cereal crops Virus disease.
