通过寄主反应、抗性鑑定、交互保护反应試驗証明,大白菜僵叶病毒是屬于黄瓜花叶病毒的一个株系。其致死温度为60℃,体外存活期为3—4天,稀释限点为1:1,000—3,000。本病第一次传染来源主要是黃瓜、西葫芦和甘兰的春夏季发病植株,由桃蚜、蘿卜蚜传播到秋白菜上。不同的白菜品种对僵叶病的抗病力有較显著的差異,抗孤丁病的品种也抗僵叶病。 Host response, resistance identification, reciprocal protection reaction test proved that cabbage leaf-dead virus is a cucumber mosaic virus. The lethal temperature is 60 ° C, the in vitro survival is 3-4 days, and the dilution limit is 1: 1,000-3,000. The first source of infection of this disease are mainly cucumber, zucchini and cabbage in spring and summer incidence of plants, from Myzus persicae, radish aphids spread to autumn cabbage. Different varieties of cabbage resistance to leaf disease have more significant differences in disease resistance, resistance to the disease is resistant to stiff leaf disease.
