本文对山东荣成流行的一种小麦病毒病进行了鉴定。提纯的病毒颗粒为长线状,13×100—300nm及13×350—650nm。汁液接种感染小麦,但不感染烟草、苋色藜等植物。病土、病根以及含有禾谷类多粘菌(POlymyxa graminis)游动孢子的浸液可以传毒于小麦、大麦及黑麦。此病毒与大麦黄花叶病毒(BYMV)、小麦梭条花叶病毒(WSSMV)有血清学关系,与小麦土传花叶病毒(WSBMV)无血清学关系。病叶表皮细胞中有无定形内含体。超薄切片可见风轮状内含体。实验结果表明,荣城地区发生的这种小麦病毒病是小麦黄花叶病毒所致。
In this paper, Shandong Rongcheng epidemic of a wheat virus disease were identified. The purified virions were long-linear, 13 × 100-300 nm and 13 × 350-650 nm. Inoculation of wheat juice, but not infected with tobacco, amaranth, and other plants. Sick soil, diseased roots and infusions containing zoospores of POlymyxa graminis can be toxic to wheat, barley and rye. The virus has a serological relationship with barley yellow mosaic virus (BYMV) and wheat splity mosaic virus (WSSMV) and has no serological relationship with wheat soil-borne mosaic virus (WSBMV). Diseased leaf epidermal cells in the presence of amorphous inclusions. Slim slice visible wind wheel-like inclusion. The experimental results show that the wheat virus disease in Rongcheng is caused by wheat yellow mosaic virus.
