| 摘要: |
| 在陕西杨陵地区,从严重受害呈现花叶症状的白芷植株上分离到一种病毒。该病毒通过磨擦接种,能侵染10科25种以上植物;TDP为65℃,DEP为10-3,L则为4天;桃蚜及蚕豆蚜不能传播,但能通过种子和汁液进行传播;可与烟草环斑病毒(TRSV)抗血清产生明显的沉淀反应;该病毒粒子呈圆球形,大小30nm。此病毒被鉴定为TRSV。 |

| Abstract: |
| A virus isolated from Angelica dahurlca showing severe mosaic symptoms in Yangling area is identified as tobacco ringsport virys (TRSV) based on following properties: The virus can infect more than 25 plant species among 10 families.Its stabilities are TDP 65℃,DEP 10-3 and L 4 days.The virus is transmitted by seed and sap but not by Myzus persieae and Aphis fabae.Agar double diffusion test indicates the virus reacts with antiserum of TRSV only.Electron microscopy reveals that the particle is about 30 nm in diameter. |
