Tobacco mosaic disease is one of the most important limiting factors to the production of tobacco in Guangdong province. The incidence of the disease was 2 to 20 per cent according to the present investigation in 8 major tobacco-growing counties in the years of 1983 and 1984.Based on the serology, morphology of virus particles, symptoms on indicator plants, host ranges, means of transmission, insect vectors,physical properties and cross protection, the causal viruses of the disease in Guangdong province were...

Tobacco mosaic disease is one of the most important limiting factors to the production of tobacco in Guangdong province. The incidence of the disease was 2 to 20 per cent according to the present investigation in 8 major tobacco-growing counties in the years of 1983 and 1984.Based on the serology, morphology of virus particles, symptoms on indicator plants, host ranges, means of transmission, insect vectors,physical properties and cross protection, the causal viruses of the disease in Guangdong province were identified to be 3 types of isolate of CMV ( CMV-C, CMV-TN, and CMV-TYN ) , Tobacco mosaic virus, Potato virus Y,Tobacco vein-banding mosaic virus ( TVBMV)and Tobacco chlorotic mottle virus (TCMV.)CMV-TYN is an unreported new isolate of CMV. It induced yellow mosaic on tobacco and N.glutinosa,and local necrotic lesions on Datura stramonium and Zinnia elegans.CMV-TN was characterized by vein necrosis on tobacco.TVBMV was detected in the mainland of China for the first time.TCMV was considered probably to be a new causal virus belonging to the PVY group.The particle length of the virus is c.710 nm. It induced chlorotic mottle on tobacco and tomato, chlorotic spots on N.glutinosa.TIP 55-60, DEP 10-2-10-3, longevity in vitro 4-8 days.It differs from TVMV, TVBMV, PV-MV, and PVY in serology, and other members of the PVY group reported in host range. Of 155 specimens of diseased plants collected, 127 were successfully transmitted mechanically.The distribution and ratio of the viruses identified were as follows: CMV, 8 counties and 70%; TCMV, 6 counties and 12.1%; TMV, 4 counties and 9.8%, TVBMV, 2 counties and 2.2%; PVY, 1 county and 6%.

烟草花叶病是广东省产烟区的主要病害之一。我们在南雄等八个县进行调查,1983年至1984年的一般发病率为2~20%。根据血清学反应、病毒粒体形态、鉴别寄主反应及寄主范围、媒介昆虫种类、物理性质、交互保护反应等各项检验结果,鉴定广东省烟草花叶病病原是:三个黄瓜花叶病毒可能株系(普通株系CMV-C,烟草坏死株系CMV-TN,烟草黄色坏死株系(CMV-TYN),烟草花叶病毒(TMV),马铃薯病毒Y(PVY),烟草脉带花叶病毒(TVBMV)和烟草褪绿斑驳病毒(TCMV)(暂定)。

A new virus. bect chlorotic mottle virus, has been isolated and identified for the first tise in Biology Department, Inner Mongolia University, Huhhot. The virus had a strong affinity to Chenopodiaceae plants, and scarcely infected plants of other families. On diseased sugar beet ap peared systemical chlorotic blotches, and four species of Chenopodium plants infected produced local necrotic spots and systemical apical necrosis. Physicochemical tests showed that the virus lost infectivity when diluted 10~(-3), kept for 10 hrs at 10 — 15℃, and heated for 10 min. at 45℃. The virus particles, about 70—90 nm in diameter, are roughly spherical, containing an envelope structure, which can be removed by Triton X-100 to leave the viral capsids which are about 55—60 nm in diameter and more uniform in morphology. Observations on thin sections of cells from chlorotic leaf tissue of infected sugar beet showed that there were virus particles only in cytoplasm always with dense granular and diffuse materials.

本文报导一种甜菜退绿斑驳病毒的分离和鉴定。这种病毒对藜科植物有较强的亲和力,而难以侵染茄科及其它科植物。感病的甜菜表现为系统的退绿斑驳,其它藜科植物则产生局部枯斑、坏死斑及系统顶端坏死。物理化学性质测定表明,这种病毒在体外很不稳定,致死温度为40—45℃;;稀释限点10~(-2)—10~(-3);;体外存活期仅有8—10小时(10—15℃)。病毒粒子含有脂类性质外膜酸球形、椭圆形或其它不规则形态,直径约70—90nm,当用无离子洗涤剂处理除去外膜后,剩下形态较规则的球形核衣壳部分,直径约55—60nm.。超薄切片观察表明,病毒粒子存在于细胞质中,并总是伴随着细胞质浓密染色物质出现。

从南京郊区表现褪绿斑驳症状的豌豆病株上分离得到的 P-12分离物,汁液摩擦接种10科42种植物,可侵染其中的8科17种植物,被侵染的小白菜(Brassica chinensis)、白菜(B.pekinens)出现典型的花叶症,油菜(B.canpestris)的接种叶出现坏死斑并发展为系统坏死,被侵染的豌豆(Pisum sativum)出现褪绿斑。体外抗性:钝化温度55~60℃,稀释限点10~(-4)~10~(-5),25℃下体外存活期2~3天。病毒粒体线形,平均长度为736nm,病叶细胞质内有风轮状内含体。在琼脂免疫双扩散及免疫电镜试验中,能与芜菁花叶病毒的抗血清呈阳性反应。根据上述特征,P-12被鉴定为芜菁花叶病毒。该分离物不能通过桃蚜(Myzus persicae)、豆蚜(Aphis craccivora)、豌豆蚜(Acyrthosiphon pisum)以非持久性和半持久性传毒。所测定的8个品种均能受其感染。
