花生病毒病是花生的主要病害之一。最近几年来,在我国的辽宁、山东、江苏、安徽、河北,河南、北京等省市的花生产区,都普遍发生。据1977～1979年大连地区调查,因病毒病为害,使花生减产10～20%。为了查清这一病害的发病规律和控制逐年蔓延,大连市农科所与中国科学院林土所对这一病害,进行了多次田间调查、温室试验及病毒的提纯和电镜观察,本文仅报导了汁液摩擦、切接、靠接等方法的传毒试验结果,从而确证了目前在我国花生上普遍发生的花叶病和斑驳病(Peanut mottle Viws and Peanut masaicViws)皆可通过嫁接、汁液摩擦等机械伤口方式传毒。一、材料和方法从1979年在田间已经感染病毒病的“锦交
Peanut virus disease is one of the major peanut diseases. In recent years, flower production areas in China’s Liaoning, Shandong, Jiangsu, Anhui, Hebei, Henan and Beijing provinces and cities have generally occurred. According to a survey conducted in Dalian from 1977 to 1979, peanut production was reduced by 10 to 20% due to virus damage. In order to find out the regularity and control of the disease’s disease spread from year to year, Dalian Institute of Agricultural Sciences and Chinese Academy of Forestry of the forest and soil for this disease, conducted several field surveys, greenhouse experiments and virus purification and electron microscopy, this article only reported The juice friction, cut connection, docking and other methods of transmission test results, thus confirming the prevalence of peanut mosaic disease and mottle (Peanut mottle Viws and Peanut masaicViws) can be grafted, juice friction, etc. Wound way of mechanical poisoning. First, materials and methods From 1979 in the field has been infected with the virus disease "Kam Kam
