In this study, PAL activity in stems of pepper (Capsicum annuum L.) plants infected by the root rot pathogen Phytophthora capsici-22 in a resistant (PM-702) and two susceptible (Kahramanmaraş-Hot (KM-Hot) and Demre-8) cultivar were studied. The response of the PAL activity in the resistant cultivar was faster and higher than in the susceptible cultivars (p < 0.01). The increase in production of PAL upon Phytophthora capsici-22 were higher in the infected plants compared to the non-infected (control) plants (p < 0.01) . An early induction of PAL was observed in the stems of three peppers infected with P.capsici within two days.
