| 摘 要： | 1983年7月,从山东薛城的花生上分离到一个病毒分离物PS-34,以汁液摩擦接种测定了9科48种植物,PS-34可侵染6科15种植物,在苋色藜上表现系统花叶。由桃蚜、豆蚜以非持久性方式传病。体外抗性测定,失毒温度50-55℃,稀释限点10-3-10-4,体外存治期3-4天.提纯后经电镜观察,病毒粒体呈球形,直径±29nm.提纯病毒的抗血清和花生矮化病毒日本株系(PSV-J)的抗血清交互测定,都与PS-34有明显的沉淀线反应。故将病毒分离物PS-34鉴定为黄瓜花叶病毒组的花生矮化病毒(PSV)。因苋色藜和昆诺藜上表现为系统花叶,与在寄主反应上明显不同.因此,确定其为一种新的花生矮化病毒PSV-C株系.

| Abstract: | The virus isolate PS-34 was obtained from an infected peanut plant showing mosaic and severe stunting in Shandong province.It infected 15 of 48 species from 6 of 9 families by sap inoculation.Mosaic was developed on Chenopodium amaranticolor.The virus was easily transmitted by Myzus persicae and Aphis craccivora in nonpersistent manner. |
