| 摘要: |
| 试验结果表明,气候斑点病、蚀纹病(TEV)及花叶病(CMV、TMV)对烟叶的产量损失分别为10.5％～53.5％,16.5％～61.5％,15％～45.5％;经济损失分别为30.4％～78.8％,43.0％～74.0％,37.2％～70.3％。经测定化学成分,烟叶受三种病害感染后,尼古丁含量显著下降,各项化学成分不协调,也不在适宜范围之内。 |

| Abstract: |
| The experimental results showed that the yield losses caused by climatic spot disease, TEV, CMV and TMV were 10.5%- 53.5%, 16.5%- 61.5%, 15.5%-45.5% respectively; and economic losses were 30.4%-78.8%, 53.0%-74.4%, 37.2%-70.3% individually. Particularly the analysis of chemical components of tobacco leaves showed that the nicotine level decreased by 0.1% - 1.22%. Significantly, the levels of other chemical components were not in due suitable range and in due proportion. |
