油菜病毒病的病毒有三种类型,即蕪菁花叶病毒、烟草花叶病毒和黄瓜花叶病毒,但主要为害的是蕪菁花叶病毒。传病的方式是:当油菜收获后,通过蚜虫这个媒介把病毒传至夏季生长的十字花科植物上;到了秋季油菜出苗后,又借蚜虫把病毒从越夏寄主传回油菜。种子不传病;新鮮病体在土壤中虽能引起植株发病,但发病率很低。因此,研究油菜病毒病常用的蚜虫接种和汁液摩擦接种,这两种方法均能誘致油菜的高度发病。由于汁液摩擦接种方法比較簡便,应用广泛。故将有关这一方法的接种技术和个人工作体会綜述如下,供参考。
There are three types of virus of rape virus disease, namely turnip mosaic virus, tobacco mosaic virus and cucumber mosaic virus, but the main damage is turnip mosaic virus. Way of transmission is: when the rape harvest, through the aphids this virus spread to the summer growth of cruciferous plants; to rape after the emergence of autumn, but also by aphids to the virus back from the summer host rape. Seeds do not get sick; although fresh pathogens can cause disease in soil, their incidence is very low. Therefore, aphid inoculation and juice friction inoculation, both of which are commonly used in the study of canola virus disease, can induce a high incidence of rapeseed. Due to the juice friction inoculation method is relatively simple, widely used. Therefore, the vaccination techniques and personal working experience about this method are summarized as follows for reference.
