| 摘 要： | 在1985年4月蚕豆病毒病的调查中,先后在四川、湖北、江苏和浙江4省的秋播蚕豆试验区内都发现一种由种子带毒的蚕豆染色病毒(BBSV)。所有病株都发生在由叙利亚国际旱地农业研究中心供种的试验区内,约10-40%的小区或品系发病,株发病率在0-18%之间。病害是随种子传入我国的。 病株为系统感染,病株叶片上的症状可以是轻花叶、斑驳、褪色斑或畸形,有的小叶正常而无明显病变。病毒粒体为等径球状体,直径28毫微米。病毒样本能与英g国染色病毒的抗血清发生沉淀反应,但与真花叶病毒的抗血清不发生反应。在病株上未发现能传毒的象甲,也无象甲的为害状,病毒病尚未扩散。在试验区以外的农田里未发现有蚕豆染色病毒存在。 |

| Abstract: | In a survey of virus diseases of faba beans in April 1985,seed-borne broad bean stain virus (BBSV)was detected in autumn sown experimental trails in four provinces,namely Hubei,Jiangsu,Sichuan and Zhejiang.Incidence in different cultivars and seed lines ranged from 0-18%.All seed used in those trails come from The International Center for Agricultural Research in Dry Areas (ICARDA). Symptoms in leaves of infected plants ranged from a mild to coarse mosaic or mottle,sometimes with leaflet malformation;some leaves appeare normal.The Virus has spherical particles about 28 nm in diameter and was identified by double diffusion serology using an antiserum to a British isolate of the virus. No weevil vectors (Apion spp.and Sitona spp.)were seen on the faba beans and no evidence of feeding damage or virus spread by weevils was found.Probably all infected plants in those trails (ICARDA's trails) had been infected through the seed. BBSV was not detected in farm crops which seeds come from Chinese origin or native. |
