ABSTRACT
Fruits are one of the most important sources of polyphenols for humans, whether they are consumed fresh or as processed products. To improve the phenolic content of fruits, a novel field of interest is based on results obtained using elicitors, agrochemicals which were primarily designed to improve resistance to plant pathogens. Although elicitors do not kill pathogens, they trigger plant defense mechanisms, one of which is to increase the levels of phenolic compounds. Therefore, their application not only allows us to control plant disease but also to increase the phenolic content of plant foodstuffs. Pre- or post-harvest application of the most commonly used elicitors to several fruits is discussed in this review.
