Abstract

The nature of the resistance of potatoes to common scab caused by Streptomyces scabies is not fully understood. The identification of chlorogenic acid in the periderm layers of potato was established by the use of paper chromatography and u.-v. absorption technics. Since vars. highly susceptible to scab contained only about one-half the amt. of chlorogenic acid of that in scab-resistant vars., it is concluded that this compound serves as a protective agent against the invasion and spread of S. scabies. The mechanism of this resistance by chlorogenic acid is still under investigation.
