Abstract
The resistance interactions of four tomato cultivars to five Rhizoctonia solani isolates, causing foot rot, were investigated. Priming H2O2 accumulation, peroxidase and ascorbate peroxidase activity was observed in CH Falat, as a partially resistant cultivar. Maximum peroxidase activity in CH Falat was observed at 24 h post inoculation (hpi) which was earlier than maximum phenolics accumulation at 72 hpi. In addition, application of peroxidase inhibitor reduced phenolics level. Therefore, peroxidase might be involved in phenolics production, as an effective resistance mechanism in our pathosystem.
