我国福建和湖南水稻东格鲁病的两个分离物──闽株2号和湘株1号,与菲律宾的菲株1号,在电镜下均能见到水稻东格鲁球状病毒(RTSV)粒体,直径为30—33nm,闽株2号和菲株1号尚能见到水稻东格鲁杆状病毒(RTBV)粒体,大小在(35×150)—280nm,而湘株1号则否:闽株2号和菲株1号,与RTSV和RTBV都有血清学关系,而湘株1号只与RTSV有关;3个分离株均能以黑尾叶蝉、二点黑尾叶蝉和电光叶蝉为其介体,并作半持久性传毒,但3种介体对3个分离株的亲和力、获毒时间、传毒时间及其在TN1和Sukanandi两个水稻品种上的反应特征都有不同:通过交叉接种,菲株1号和闽株2号不能侵染已被湘株1号侵染的植株。
Two isolates of Donggelu disease in Fujian and Hunan Provinces-Min-2 and Xiang-Zhu-1 and Philippine-1 were observed under electron microscope. Granules with a diameter of 30-33nm, Minhang 2 and Ficus 1 can still see the grain of the rice Donggeru baculovirus (RTBV), size (35 × 150) -280nm, and Xiang Zhu 1 No: Min-2 and F-1 had serological relationship with RTSV and RTBV, while Xiang-1 was only related to RTSV. All three isolates could be identified as black-tailed leafhopper, Cicadae and electro-optic leafhopper were used as mediators and were semi-persistent. However, the affinity of the three mediators to the three isolates, the time of virulence, the time of virulent transmission and their effects on two rice cultivars TN1 and Sukanandi Response characteristics are different: by cross-inoculation, Philippine strain No. 1 and Min 2 strains can not be infected Xiangdan 1 infected plants.
