| 摘 要： | 对不同遗传类型的7个烟草品种设计水杨酸（SA）预处理与对照，而后进行TMV接种和挑战接种，调查这些品种的响应程度，发现对TMV侵染的响应可分为花叶和枯斑反应2种类型，在两个对TMV侵染具有系统获得抗病性（SAR）特性的烟草品种中，品种HZNH在病斑数量、形态及大小等方面与前人已沿用多年的品种Xanthi-nc存在明显差异，且两者对于SA预处理后再接种的响应也不一样。 |

| Abstract: | tobacco varieties were treated with salicylic acid (SA), then inoculated and challenge inoculated with mosaic virus (TMV) so that responses of these cultivars to TMV were investigated. The response types could be classified into mosaic leaves, necrosis lesions. Two varieties, Xanthi nc and HZNH, showed systemic acquired resistance (SAR). The cultivar HZNH, compared with Xanthi nc, which has been used to study SAR for many years, showed significant differences in number, shape and size of necrosis lesions. There were also significant different responses to the treatment inoculated after SA treatment between the two varieties. |
