The results indicate that the elicitors SA and CHT induced effective defense responses in tomato plants against R. Cinnamyl alcohol dehydrogenase activity increased to the maximum at 48 hpe under the influence of CHT. The activity of polyphenol oxidase increased several folds by the elicitors. The peroxidase activity was about 86 nkat/mg protein at 24 hpe in case of SA and 78 nkat/mg protein in case of CHT. At 24 h post-elicitation (hpe), the activity of phenylalanine ammonia lyase was 4.5 times higher than control elicited by CHT. Most pronounced increase in lignin synthesis was triggered by SA followed by CHT. The increase in total phenolic content of roots by the elicitors was significantly higher than control. We investigated on important parameters of induced resistance in hydroponic tomato ( Solanum lycopersicum) against Ralstonia solanacearum using the elicitors chitosan (CHT), salicylic acid (SA), and jasmonic acid (JA).
