从两年(1981—1982年)四季自南京市郊11个公社和本所共采集763个番茄病毒病标样,测试结果,不论何种栽培方式,春季以T M V为主,占52.2—56.9%,C M V占34.2—34.6%,秋季以C M V为主,占74.2一78.1%,T M V只占14.4—15.6%。再从65份代表毒株在亮黄烟上测定,T M V番茄系占96.8%,T M V番茄系和烟草系混合感染占3.2%。并以 P elham 0株系占多数,广泛分布南京市郊,达总标样的76.9%;P elham1株系只发生在本所和个别公社的少数大队,占13.8%, Pelham2株系仅在本所个别番茄品种上露头,占9.2%;病毒提纯液经电镜观察,病毒粒体呈棒状颗粒。番茄条斑病是南京市郊危害番茄生产的潜在威胁,根据标样分析,以TMV和CMV单一条斑为主,极少二者的复合感染,TMV+ PVX或其他复合感染尚未发现,标样中有30份表现各式病毒症状的毒株,不明所属,有待今后进一步探讨。
A total of 763 tomato virus disease samples were collected from 11 communes in suburb of Nanjing and our institute in four seasons in two years (1981-1982). The results of the test, regardless of the cultivation method, were mainly T M V in spring, accounting for 52.2 -56.9%, C M V accounted for 34.2-34.6%, C M V dominated in autumn, accounting for 74.2-78.1%, T M V only accounted for 14.4-15.6% . Tested on bright yellow tobacco from 65 representative strains, T M V tomato accounted for 96.8%, T M V tomato and tobacco mixed infection accounted for 3.2%. And accounted for 76.9% of the total standard samples in the suburbs of Nanjing. P elham1 strain occurred only in a few brigades of the stock and individual communes, accounting for 13.8%. Pelham2 strain Only in our own individual varieties of tomato outcrop, accounting for 9.2%; virus purified by electron microscopy, the virus particles were rod-shaped particles. Tomato leaf spot is a potential threat to the tomato production in the suburbs of Nanjing. According to the standard analysis, single spot of TMV and CMV are the main symptoms. Few of the combined infections, TMV + PVX or other complex infections have not been found yet. 30 strains of various virus manifestations of the virus, unknown affiliation to be further explored in the future.
