Difference of Micro-HR to Tobacco Mosaic Virus between Nicotiana Glutinosa and N. tabacum var. Samsun NN

摘要: 以5 个浓度的TMV 溶液分别接种三生烟和心叶烟，对其产生枯斑的形态、数目和大小进行了分析比较。结果显示，两烟草接种TMV 后产生的枯斑在形态上没有差异；心叶烟产生的全叶平均枯斑数多于三生烟，且与接种病毒浓度的相关性显著（r=0.958，p<0.05）；在同一浓度下，三生烟叶片上形成的小枯斑数多于心叶烟、形成的大枯斑数少于心叶烟，且差异极显著（p<0.01）。

Abstract: Nicotiana glutinosa and N. tabacum var. Samsun (NN) were inoculated with TMV solution in five different concentrations, respectively. Then the shape, number and size of local necrotic lesions in different treatments were recorded and analyzed. The results showed that the shape of local necrotic lesions formed in two tobacco varieties had no difference, and there was significant difference between average number of local necrotic lesions on the leaf of N. glutinosa and virus concentration (r=0.958， p<0.05). There were more small local necrotic lesions and less large local necrotic lesions on the leaf of N. Tabacum var. Samsun (NN) than that of N. glutinosa, and the difference was very significant (p<0.01).
