芝麻黄化花叶病毒病,又称芝麻黄化卷叶病,是芝麻一种常见病害,在流行年份,给芝麻生产带来严重损失。感染病害的芝麻植株叶片出现黄色与绿色相间的黄化花叶症状,有的叶片向内卷曲或扭曲,畸形。病株表现矮化,感染早的病株严重矮化,常收不到产量。 1984年我们从油料所试验地芝麻黄化花叶病株中分离的每株进行初步鉴定。 一、病毒寄主范围测定 采用常规的人工汁液磨擦接种方法,在苗期,每种供试植物接种6—10株,观察症状表现。在测定的25种植物中,该病毒侵染10种植物,其中系统侵染6
Sesame yellow mosaic virus disease, also known as sesame yellow curl leaf, is a common disease of sesame seeds, in the popular year, to sesame production caused serious losses. Infected diseases of sesame leaves appear yellow and green yellow mosaic symptoms, and some curled or twisted inward, deformity. Disease dwarf disease performance, early infection of the infected plant serious dwarf, often can not receive the output. In 1984, we initially identified each plant isolated from the sesame mosaic mosaic strain tested in the oil. First, the virus host range determination using conventional artificial juice friction inoculation method, at the seedling stage, each test plants inoculated 6-10 strains, observe the symptoms. Of the 25 tested plants, the virus infects 10 plants, of which system infects 6
