本文主要研究甜菜黄化毒病在东北地区的症状及危害,以及病毒的提取工作。我们所观察到的弯曲杆状体属纺锤线状病毒组的代表成员甜菜黄化毒病,具有螺旋对称,螺距为3.7μm病毒颗粒长度在600—2000μm左右。基因组是一个单键RNA分子,分子量为2.3—4.3×10~6。
This paper mainly studies the symptoms and harm of beet yellow virus in northeast China and the extraction of virus. We observed that the bent rod body belongs to the beet virus belonging to the group of spindle virus and has a helix symmetry with a pitch of 3.7 μm and a virus particle length of about 600-2000 μm. The genome is a single-stranded RNA molecule with a molecular mass of 2.3-4.3 × 10 -6.
