CHLOROGENIC ACID AND VERTICILLIUM WILT OF TOBACCO

Abstract

Chlorogenic acid, which occurs in high concentrations in tobacco, has been suggested as a factor in the resistance of potatoes to both verticillium wilt and common scab. In an investigation of the relationship between chlorogenic acid content and the resistance of tobacco (Nicotiana tabacum L.) cultivars to wilt caused by Verticillium dahliae Kleb., a simple method was devised for the estimation of relative chlorogenic acid content. Results obtained suggested a possible relationship or correlation between content of chlorogenic acid and resistance of tobacco plants to verticillium wilt, and that an estimation of chlorogenic acid content might be useful when screening tobacco varieties for verticillium resistance, if accompanied by appropriate testing for susceptibility to virus infection.
