摘　　要：对烤烟漂浮育苗过程中TMV传播途径进行了研究。结果表明:各种剪叶方式均能传播TMV,而且传播效率极高,剪叶是漂浮育苗中TMV引起的烟草普通花叶病在苗期传播的最主要、最有效的途径。而受TMV污染的漂浮盘、营养液和基质是TMV在漂浮育苗中传播的主要初侵染源,但对TMV的传播效率较低。The spreading approaches of TMV in flue-cured tobacco floating seedbed system were studied. The results showed that TMV spread mainly by clipping with very high efficiency, and clipping was the most important and effective approach of tobacco mosaic spreading in floating seedbed system. The infected seedling tray, nutrient solution and medium were major sources of TMV spreading in floating seedbed system, though the spreading efficiency was relatively lower.
