摘要：

通过2006年间在美国北卡罗来那州烟草主要生产区的田间调查，系统的描述了番茄斑萎病毒侵染烤烟后，在烤烟叶片上产生的叶片畸形、镶脉、叶脉坏死、坏死斑、同心环纹、叶面皱缩，且整株出现矮化异常生长；将番茄斑萎病毒采用人工摩擦接种到本生烟上，植株被系统侵染，并产生褪绿斑坏死斑、 同心环纹、皱缩等症状，植株一般4～5周内死亡。通过比较两种寄主，发现番茄斑萎病毒侵染两种寄主均出现系统症状，症状相似，但也有不同。

Abstract:

This research (paper) systematically described symptoms after Tomato spotted wilt virus (TSWV) infacted tobacco based on the tobacco field survey in North Carolina in 2006. These symptoms included leaf deformation, vein banding, vein necrosis, necrosis spots, concentric rings, rugosity, and stunting growth. By manually mechanical inoculating tobacco plants, the plants were systematically infected and chlorotic spots, necrotic spots, concentric rings, and rugosity symptoms were induced. Finally, the plants died in 4-5 weeks. After comparing two hosts, it was found that the symptoms from two hosts infected with TSWV were similar, but with exceptions.
