【摘要】 <正> 番茄病毒病是福建番茄生产的重要病害,近年来在福州、莆田等地番茄栽培中,田间自然发病率一般多在70%以上,有的竟高达95—100%。主要表现化叶、疱斑、蕨叶,偶尔有条斑坏死和黑褐包小环斑的,病株所结果实少而小,甚至畸形,果皮有花斑,严重影响番茄产量和商品品质,给生产造成重大损失。为了寻找有效治理途径,便于"对症下药",三年来作者开展了这方面的研究,下面就病原鉴定结果作一报道。更多还原

【Abstract】 4 virus isolates were obtained from 185 samples of different tomato virus diseases collected from the suburban areas of Fuzhou,Putian,Xiamen and Longyan cities through biological isolation and purification methods from May,1984 to June,1986.They were identified as TMV,CMV,PVX and ToBRV(Tomato black ring virus)according to their reactions on different- ial hosts,detections by electron microscope and serological tests,and three physical characteristics of the viruses,in which ToBRV was first found in China to infect tomato naturally.Among the 185 samples,the rate of TMV,CMV,PVX and ToBRV was 49.19%,32.97%,16.22% and 1.62% respeetively.TMV and CMV(82.16% in total)were therefore considered to be the major pathogens of tomato virosis in the 4 cities above-mentioned. The result provided a reliable basis for the control of the diseases.更多还原
