The effects of different virus inactivation methods on seed germination properties were investigated in the present study. Certain inactivation treatments applied to essential vegetable seed such as tomato, pepper, melon, squash, bean and lettuce which are important for seed production in Turkey. For the study, 8 different seed samples infected by Tomato mosaic virus (ToMV), Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV), Soybean mosaic virus (SMV) and Lettuce mosaic virus (LMV) were exposed to virus-inactivation treatments such as chemicals, dry heat, ozone, heat water and UV. As a result of treatments in question, the germination tests were applied to seed samples and the obtained data were assessed statistically. Germination powers (%) and average germination periods (day) of seeds in our work were considered for the criteria of assessments. According to test results, other seed treatments except from HCl and ozone, reduced the germination power of vegetable seeds generally. On the other hand, germination power in HCl and ozone treatments found at the similar levels with control values. Theheatwatertreatments (65 °C) reduced the germination power of seedsfrom 94% to 34%. Consequently, HCl and ozone treatments did not have any negative effects on germination values where these treatments were also successful in elimination of viral agents
