Abstract

Abstract Accumulation of phenolic compounds (p-coumaric, caffeic, and ferulic acids and p- coumaric acid methyl ester) was followed in susceptible (Mustang) and tolerant (Flamingo) cucumber (Cucumis sativus) cultivars. The objective was to determine whether these compounds played a role in resistance against powdery mildew following a prophylactic treatment with Milsana (leaf extracts from the giant knot weed Reynoutria sachalinensis, ...
