Mechanical Injuries and Tobacco Mosaic virus (TMV) Infection

It was reported that only insufficient infection with TMV of Xanthi-nc tobacco would be resulted unless TMV was inoculated immediately after abrasion (Fig. 1), and that the wounds of trichomes of Nicotiana glutinosa leaf stalk, made with electric shaver wetted with the virus suspension were much inferior in TMV infection to the wounds made by rubbing method with abrasive (Table 1).
