| 摘 要： | 湖北五峰县是中国唯一的马里兰烟种植区。2011年在湖北马里兰烟产区进行病毒病发生情况大田调查，发现主要有花叶、畸形、脉坏死、蚀刻等4种症状类型，幵采用指示植物法对主要症状类型所含病毒的种类进行了鉴定；对采集的57份病毒病样本采用DAS-ELISA进行病毒种类的鉴定。结果表明，发生在马里兰烟上的烟草病毒种类包括TMV、CMV、PVX、PVY 和 TEV，TMV 检出率最高，PVY 次之；以2种或2种以上病毒复合侵染方式为主，其中 TMV＋PVY、TMV＋CMV＋PVY共存方式较为常见。

| Abstract: | Wufengcountyin Hubei province is the only Maryland tobacco plantingarea in China. Maryland tobaccovirus diseases wereinvestigatedtherein 2011.The symptom types ofvirusdiseases could be divided into4mainkinds, including mosaic, distortion, vein necrosis,etching, which were identified through indication plants for virus species.DAS-ELISA was applied to identify the virus speciesto the collected 57 samples. It demonstrated that the virus species which infected Maryland tobacco included TMV, CMV, PVX, PVY and TEV. The detection rate of TMV was maximal among all the tested samples, and PVY took the second place. Meanwhileit commonlyoccurredthattwo and more kinds of virus co-existed, and TMV＋PVY, TMV＋CMV＋PVY were the main patterns. |
