Abstract
This report describes a study on the effects of pectinase and hydrogen peroxide (H2O2) on previously identified phenolic compounds in the leaves of Thunbergia alata. The elicitors were found to produce lesions resulting in the loss of chlorophyll and death of the cells surrounding the point of elicitation. At the optimal concentrations, hydrogen peroxide (15%) produces, after 24 hours, lesions that are 4 to 5 times greater than the lesions produced by pectinase (20 units/ml). Pectinase stimulates both local and systemic accumulation of the most pre-existing phenolic compounds, whereas hydrogen peroxide has no or little effect on the accumulation of some of these substances. Pectinase and in a less degree, hydrogen peroxide lead to the appearance of a new phenolic compound that is not present in control plants.
