新疆五家渠地区种植的大蒜(Allium sativum)表现出退绿条斑的病状,对15个种植单位进行了实地调查,发病率达50%,一般减产20%左右。紫皮蒜的发病指数略高于白皮蒜。外来品种与当地品种发病率无明显差别。在汁液接种和渍出法的电镜观察方面获得了这种病状是由病毒引起的初步证据后,我们从寄主反应、体外抗性、传播途径、病毒形态和血清学鉴定等方面研究了大蒜退绿条斑病毒的一些性质,希望有助于生产上制定相应的防治措施。
Allium sativum planted in Wujiaqu area of Xinjiang showed the symptoms of retrogalvan patchwork. The field survey was conducted on 15 planted units with the incidence of 50% and the general reduction of about 20%. Purple garlic incidence index slightly higher than white garlic. No significant difference in the incidence of exotic species and local breeds. After obtaining the initial evidence of this pathogenicity caused by the virus in the electron microscopic observation of the juice inoculation and pickling method, we studied the greening of the garlic from host reaction, in vitro resistance, transmission route, virus morphology and serological identification Some of the nature of streak virus, hoping to help develop the appropriate prevention and treatment measures.
