Infection by a compatible race of Erysiphe graminis f. sp. hordei on barley secondary leaves was significantly suppressed upon pruning of the primary leaves when E. graminis hordei was inoculated 3–12 h after the pruning, but it, was rather enhanced during 15–21 h. The accumulation of antifungal substances was detected in hot ethanol extracts of barley seedlings from 15–27 h after pruning the primary leaves. Taking the time of the infection process of a challenger ( E. graminis, hordei ) into consideration, timing of systemic resistance induced upon pruning coincided with the accumulation of antifungal substances.
