| Abstract: | The resistance induced by oligogalacturonides to Tobacco mosaic virus was studied in fields and greenhouses. It was shown that the best induced resistance was achieved at 50 μg/mL of oligogalacturonide. The inhibition ratio of lesion was 64.4%. Furthermore, the activity of plant resistance correlated enzymes, including superoxide dismutase and catalase, could be raised by oligogalacturonides. |

| Keywords: | oligogalacturonide induced resistance Tobacco mosaic virus control efficiency |
